this Channel and my online school

play00:37

codewithmash.com if you are new here

play00:39

make sure to subscribe so you never miss

play00:41

a video

play00:42

so what exactly is chat GPT and how does

play00:45

it work chat jpt is a Cutting Edge AI

play00:48

tool created by open AI it was released

play00:51

in November 2022 and gained 1 million

play00:54

users in just 5 days in comparison it

play00:57

took Netflix three and a half years and

play00:59

Instagram two and a half months to get

play01:01

the same number of users chat gbt is an

play01:04

advanced language model that can

play01:06

understand and generate text you can use

play01:08

it to create content for your website

play01:10

write articles emails tweets cover

play01:13

letters and so on you can also use it to

play01:15

generate code in a number of different

play01:17

programming languages like python

play01:18

JavaScript HTML CSS and much much more

play01:22

you can use it to generate dummy data

play01:24

write unit tests translate text or code

play01:27

from one language to another you can use

play01:29

it to explain code for example if there

play01:31

is a piece of code you don't understand

play01:32

you can ask it and it will explain to

play01:34

you like a patient teacher but I have to

play01:37

be honest sometimes it explains too much

play01:39

chat GPT can also help you learn and

play01:42

remember things faster for example you

play01:44

can give it some text and have it ask

play01:46

you a bunch of questions it can also

play01:48

prepare you for job interviews you can

play01:50

have it improve your resume write a

play01:52

cover letter for you and also interview

play01:54

you like an interviewer now do you think

play01:57

chat GPT is going to take your job let

play01:59

me know in the comments below the

play02:00

reality is whether you like it or not

play02:02

chat GPT is here to stay in this

play02:05

tutorial I'm going to show you how to

play02:06

use it to get more creative and get

play02:08

things done a lot faster I'll be showing

play02:11

you various examples for different

play02:12

programming languages both for beginners

play02:15

and experienced developers but before we

play02:17

dive into that let's take a moment and

play02:19

understand how chat gbt works chat GPT

play02:23

uses a type of artificial intelligence

play02:25

called a language model a language model

play02:28

is a type of software that is designed

play02:30

to understand and generate human

play02:32

language it does this by looking at a

play02:35

large amount of Text data and learning

play02:37

the patterns and rules of a language for

play02:40

example if the language model is trained

play02:42

on a lot of English texts it will learn

play02:44

about the grammar and structure of

play02:46

English as well as the meanings of words

play02:48

and how they are used in different

play02:50

contexts once the language model has

play02:52

learned about a language it can then be

play02:54

used to generate text in that language

play02:56

now chat GPT provides different language

play02:59

models for different purposes gpt3

play03:02

models which are designed to understand

play03:04

and generate natural language like

play03:06

English and codecs which are

play03:08

specifically trained to understand and

play03:10

generate code these models are trained

play03:13

on billions of lines of code publicly

play03:15

available on GitHub they're mostly

play03:17

capable in Python but they're also

play03:19

pretty good in a bunch of other

play03:20

languages like HTML CSS says JavaScript

play03:23

typescript Ruby SQL and more now before

play03:27

we look at specific examples remember

play03:29

shot GPT like any tool has limitations

play03:32

it might sometimes generate incorrect

play03:34

harmful or biased information so don't

play03:37

take whatever it tells you as a silver

play03:39

bullet don't use it to learn to code

play03:41

because the code that is generated is

play03:43

not guaranteed to be right it might be

play03:45

functional but it might not be the best

play03:47

way to code so in a nutshell chatgpt is

play03:51

a powerful tool that can help you be

play03:52

more creative and efficient but it's not

play03:55

a substitute for human expertise and

play03:56

judgment so that's the theory part now

play03:59

let's move on and see chat GPT in action

play04:01

so head over to

play04:03

chat.openai.com if you don't have an

play04:05

account sign up it takes only a minute

play04:08

once you have logged in you're going to

play04:10

see the main screen with an input box to

play04:12

talk to chat GPT there is also a Chrome

play04:14

extension and a desktop application

play04:16

available if you don't want to use the

play04:18

web interface I'll put the links down

play04:20

below this video alright now let's get

play04:22

to the fun part going forward I'll be

play04:24

showing you various use cases for

play04:26

different programming languages we'll

play04:28

start off with some general purpose

play04:30

questions that apply to anyone

play04:31

regardless of the programming languages

play04:33

and tools they use you will see how you

play04:36

can use chat GPT to learn new things

play04:38

write shell scripts get commands start a

play04:41

business write legal documents and so on

play04:44

once we cover the basics then we'll dive

play04:46

into specific examples for front-end

play04:48

back-end and database development I will

play04:51

show you examples using HTML CSS

play04:54

JavaScript typescript python SQL and

play04:57

more

play05:00

now here's my first question what are

play05:02

the top three books for learning Java

play05:12

all right as you can see chat GPT has

play05:14

given us a very comprehensive and

play05:16

detailed answer now here we can ask more

play05:18

detailed questions for example we can

play05:21

ask questions about the first book so we

play05:23

can ask what are the key takeaways from

play05:27

head first Java

play05:34

all right another comprehensive answer

play05:36

you can see that this book teaches you

play05:39

about object-oriented programming Java

play05:42

fundamentals threading and concurrency

play05:44

GUI programming and so on now we can

play05:47

also ask more general questions like how

play05:49

do I become a front-end developer

play05:58

so now chat GPT is saying that to become

play06:01

a front-end developer you need to know

play06:03

the basics of HTML CSS and JavaScript

play06:06

you should practice building websites

play06:09

then you should learn a front-end

play06:11

framework like react angular View and so

play06:13

on you should also know about Version

play06:15

Control Systems like git GitHub and Swap

play06:18

this is pretty much the same answer you

play06:20

will find on every website that gives

play06:22

you a roadmap to become a front-end

play06:25

developer

play06:26

now let's look at more specific examples

play06:28

we can ask chatgpt to write a shell

play06:31

command for us for example we can say

play06:33

write a bash command to find the name of

play06:36

all JPEG files in the directory and

play06:40

write them all to a text file

play06:43

take a look

play06:48

I love this answer so if you're not good

play06:51

with Linux commands you can easily find

play06:54

the final instruction you should use to

play06:56

solve that problem but what is beautiful

play06:58

about chatgpt is that it also explains

play07:01

how this command Works line by line

play07:03

piece by piece we can also have chat GPT

play07:07

red git commands for us for example we

play07:09

can ask how do I know

play07:11

how many lines of code

play07:14

I've committed to a git Repository

play07:22

we can also use chat GPT to get creative

play07:25

for example let's say you want to start

play07:27

a business you can have chat GPT

play07:29

generate app or website names for you

play07:31

for example we can say I want to make a

play07:35

revolutionary online shopping app give

play07:39

me some good app names

play07:46

so chatgpt is suggesting names like shop

play07:49

is Swift cart streamline and so on I

play07:52

think this list is pretty damn good now

play07:54

these are just some example prompt you

play07:56

don't need to use the exact same wording

play07:58

to talk to chat GPT you can ask any

play08:00

questions you want in your own way now

play08:03

if you have used this tool before let us

play08:05

know in the comments below the

play08:06

interesting questions you have asked so

play08:08

we can all learn and Inspire each other

play08:10

we can also ask chat GPT to write

play08:13

contracts for us here's an example I

play08:16

want to hire a graphic designer to

play08:18

design a website

play08:20

we have agreed

play08:22

that they will deliver the first draft

play08:25

in two weeks and offer three iterations

play08:29

free of charge

play08:31

any iteration after will be charged

play08:34

at fifty dollars an hour write a

play08:37

contract for us so the more details we

play08:40

give to chat GPT the better response

play08:43

we'll get

play08:48

all right take a look

play08:50

this is a pretty damn good contract to

play08:53

start with of course you don't want to

play08:54

take this as is and use it in the real

play08:56

world without first passing it by a real

play08:58

lawyer that's why earlier I told you

play09:01

that chat CPT is not a replacement for

play09:02

humans at least none at the moment it's

play09:05

just a way to increase your productivity

play09:07

and get things done in less time

play09:09

now if you're applying for a job there

play09:11

are a number of ways chat GPT can help

play09:13

you for example you can have it write a

play09:15

resume for you hear me can say I have

play09:18

three years of experience coding in HTML

play09:22

CSS and JavaScript

play09:24

write a resume for me of course we can

play09:27

give it more details we can explain our

play09:29

education level our past projects and so

play09:32

on but look at what we get with this

play09:34

simple prompt

play09:39

all right take a look

play09:42

so chat GPT created a basic layout

play09:45

that includes our name address phone

play09:48

number email some objective summary

play09:51

technical skills and it has already

play09:53

listed all the related web Technologies

play09:56

so we have HTML CSS JavaScript jQuery

play10:00

bootstrap we didn't mention any of this

play10:02

but it assumed that we have these skills

play10:04

it also included a section about

play10:06

professional experience including past

play10:08

projects as well as education

play10:12

certifications and so on again it's a

play10:15

great starting point now let's say

play10:17

you're applying for a front-end

play10:18

developer role you can ask chatgpt to

play10:21

write a cover letter for you that you

play10:23

can email to that company so we can say

play10:26

applying for a front and engineer role

play10:30

at some company

play10:32

write a cover letter for me

play10:40

all right take a look

play10:41

we have a comprehensive cover letter

play10:43

beautifully written in perfect English

play10:46

how good is that now let me show you

play10:48

another fun one you can have chat GPT

play10:50

ask you interview questions we can say

play10:53

act as a technical interviewer and ask

play10:57

me five questions about JavaScript

play11:00

take a look

play11:07

all right so here we have five questions

play11:09

that are often asked in technical

play11:10

interviews now let's say you don't know

play11:12

the answer to the first question you can

play11:14

ask a follow-up question so the beauty

play11:17

of chat GPT is that it remembers

play11:19

everything you have told it in this

play11:21

conversation thread so here we can say

play11:23

what is the answer to the first question

play11:32

again we get a very comprehensive

play11:34

detailed answer you can also ask chat

play11:37

GPT to help you write emails for example

play11:40

we can say write an email to my boss

play11:43

asking for a raise

play11:45

I've worked at this company

play11:47

for two years and successfully

play11:50

delivered several projects

play11:54

on time

play12:01

seriously if I wanted to write this

play12:03

myself it would take me 10 to 15 minutes

play12:05

if not longer I got the answer in just

play12:08

two seconds

play12:09

all right now let's look at a few

play12:11

examples involving code we'll start with

play12:13

using python for writing a command line

play12:15

tool we can say write a python function

play12:19

for generating a random password

play12:29

so as you can see we get a piece of code

play12:31

beautifully highlighted with explanation

play12:34

of how it works now if there's a part of

play12:36

this code that you don't understand you

play12:38

can always ask follow-up questions for

play12:41

example we can ask what this expression

play12:43

does in this code so we can ask what

play12:46

does

play12:47

4 in I range of length 2 in this code

play12:53

take a look

play12:58

really really useful couldn't be better

play13:01

now we can also ask computer science

play13:03

questions like what is the time

play13:06

complexity of this function

play13:09

now if you're not familiar with this

play13:11

concept time complexity is a way to

play13:13

explain how large inputs impact the

play13:16

performance of an algorithm it's really

play13:18

beyond the scope of this tutorial I've

play13:20

covered it in detail in my data

play13:22

structures course in case you're

play13:24

interested so let's see what we get

play13:31

so chat GPT is saying that this

play13:33

function's time complexity is linear now

play13:36

let's take this to the next level we can

play13:38

ask chatgpt to write unit tests for this

play13:41

function so write unit tests for this

play13:44

function

play13:51

seriously how good is this if I wanted

play13:53

to write all this unit tests by hand it

play13:55

would take me probably 20 to 30 minutes

play13:57

if not longer of course we should always

play13:59

use our own judgment to make sure that

play14:01

the tests are correct but I think this

play14:03

code is a great starting point and it

play14:05

really saves us a lot of time

play14:07

we can also ask chat GPT for ideas to

play14:10

improve our code for example here on

play14:13

w3schools.com we have this piece of

play14:16

python code where we use a for Loop to

play14:19

iterate over a list of fruits if the

play14:21

fruit has a in it then we add it to a

play14:24

new list I'm going to copy this code and

play14:27

give it to chat GPT to see how we can

play14:29

improve this code so take a look

play14:32

how can I improve this code now here we

play14:36

should hold shift and then press enter

play14:37

so we go to the next line now we paste

play14:40

our code and then press enter to submit

play14:42

the question

play14:48

all right look a lot of details

play14:51

absolutely amazing one thing I love here

play14:53

is that chat apt is suggesting to use a

play14:56

list comprehension which is a one-liner

play14:59

for implementing the same logic of

play15:01

course there are more ways to improve

play15:03

this code we are not going to get into

play15:04

details here

play15:05

we can also ask chat jpt to convert our

play15:08

code from one language to another for

play15:10

example we can say convert this python

play15:13

code to JavaScript

play15:18

foreign

play15:21

just a few seconds our code was

play15:24

converted to JavaScript and down below

play15:26

we have all the details about how this

play15:29

code works

play15:31

we can also use chat CPT to generate

play15:33

dummy data for example we can say

play15:36

generate dummy data for a table called

play15:39

customers each customer should have an

play15:43

ID

play15:44

first name last name and City

play15:52

now in this case chat GPT gave us a

play15:55

python script for generating dummy data

play15:58

but what if we want the actual data not

play16:00

a python script we can say I don't need

play16:03

a python script just give me the data

play16:13

so now we get a list of 10 people

play16:16

represented using the Json format now we

play16:19

can take this to the next level and say

play16:21

create a python class for storing these

play16:25

objects

play16:28

foreign

play16:31

look we get an example of a python class

play16:34

called customer

play16:36

along with how we can use this class to

play16:39

store a bunch of customer objects inside

play16:42

the list absolutely beautiful

play16:44

now if you're a front-end developer you

play16:46

can ask chat jpt to generate some HTML

play16:49

markup for you and this is where

play16:51

examples get more and more interesting

play16:54

for example we can say write the HTML

play16:56

and CSS code for displaying a card

play17:01

foreign

play17:06

take a look we have the markup here we

play17:09

have a div with the class of card inside

play17:12

the div we have an image then we have

play17:14

the card content inside this div we have

play17:17

the card title and cart description

play17:19

really really good and right below that

play17:22

we have all the CSS we need

play17:24

to display a beautiful card of course we

play17:27

probably need to customize this but

play17:29

again this is a great starting point now

play17:32

we can stop here or we can customize

play17:34

this further for example we can say add

play17:37

a button below the card content

play17:41

foreign

play17:46

look what happened so now we have a new

play17:49

markup right under the card description

play17:52

we have a new div with the class of card

play17:54

action and inside this div we have a

play17:57

button beautiful now we also have more

play18:01

styles for this button we have the plane

play18:03

Styles as well as the styles for the

play18:05

hover effect now let's take this to the

play18:08

next level we can say when I hover my

play18:10

mouse over the card

play18:13

I want the card to slightly slide up

play18:22

so charge if it is suggesting that we

play18:24

should use the hover sudo class and the

play18:27

translate function Translate Y to slide

play18:30

the card up beautiful I love it it's

play18:33

also suggesting an alternative solution

play18:35

using box Shadow so it's pretty up to

play18:37

speed with CSS features now let me show

play18:39

you something really cool we can ask

play18:41

chat GPT to rewrite this code using

play18:43

Tailwind CSS if you're not familiar with

play18:46

Tailwind it's a CSS library that has

play18:48

gained a lot of popularity lately so

play18:51

here we can say can you rewrite this

play18:54

code using Tailwind CSS

play18:59

foreign

play19:04

there you go now we have the same markup

play19:07

but with the utilityclasses that come

play19:09

with Tailwind CSS so we don't have to

play19:12

create CSS classes anymore now here we

play19:14

can get more creative and see what other

play19:17

UI libraries are supported

play19:19

next we can bring some JavaScript to the

play19:21

mix and make this interactive so we can

play19:24

say when I click on the button

play19:27

send an HTTP request to slash API slash

play19:30

products

play19:32

foreign

play19:37

let's look at the generated code so chat

play19:40

GPT is suggesting to use the fetch API

play19:43

that is supported in pretty much most

play19:45

modern browsers but I personally don't

play19:47

like to use the fetch API so I'm going

play19:49

to customize this further and say

play19:51

instead of the fetch API use axis which

play19:55

is a library for sending HTTP requests

play19:58

now take a look

play20:04

all right now we have the instructions

play20:06

for installing axios using npm or yarn

play20:10

as well as a modified example using axis

play20:13

beautiful

play20:15

we can also ask chat GPT to help us with

play20:18

compile time or runtime errors here is

play20:20

an example let's say as part of writing

play20:22

some JavaScript code we got an error

play20:24

saying uncut type error cannot read

play20:28

property let's say bar of undefined

play20:31

anyone who has written a little bit of

play20:33

JavaScript code has probably come across

play20:35

this error so we can copy paste the

play20:37

error message here

play20:39

now chat GPT explains exactly what this

play20:42

error is and how we can potentially

play20:44

solve it

play20:49

so going forward I think a lot of people

play20:51

will start to use chat GPT instead of

play20:53

Google

play20:55

now we can also throw react here and

play20:57

make the example more interesting so we

play20:59

can say create a react component for

play21:02

displaying a card

play21:09

all right let's see what's happening

play21:11

here so up here we have an example of a

play21:14

function component for displaying a card

play21:16

now I personally don't like to have a

play21:19

parameter called props it would be nicer

play21:21

to destructure this parameter and grab

play21:24

individual properties like title

play21:26

description and so on so if you're not

play21:28

familiar with this concept don't worry

play21:29

just continue watching we're not going

play21:32

to do a lot of fancy JavaScript stuff in

play21:34

this video this is just to open your

play21:36

eyes to the possibilities so let's take

play21:39

this to the next level and say this

play21:41

structure the props parameter so the

play21:45

beautiful thing about chat GPT is that

play21:47

it remembers our conversations so let's

play21:50

go ahead

play21:53

foreign

play21:57

we have a new implementation of the card

play21:59

component with the props parameter

play22:01

destructured

play22:03

all right now let's move on and look at

play22:05

a few examples involving back-end

play22:07

development for example we can ask chat

play22:09

jpt to build an API for us with node and

play22:12

express so here we can say I need an API

play22:15

built with

play22:17

express.js to return the list of

play22:20

products

play22:21

each product should have attributes like

play22:25

ID title description price and image URL

play22:31

thank you

play22:36

all right look at this implementation in

play22:38

this implementation we have an area of

play22:41

products stored in memory and we have an

play22:43

API endpoint exposed at this URL I don't

play22:47

want to have an area of products in

play22:48

memory I want this product to be stored

play22:51

in a mongodb database so here we can say

play22:54

modify the code and retrieve the

play22:57

products

play22:58

from a mongodb or a MySQL or a postgres

play23:02

whatever database

play23:04

now we get a new implementation where

play23:07

products are retrieved from a mongodb

play23:10

database using the Mongoose Library

play23:13

here it is

play23:17

now in this implementation the type of

play23:19

these parameters is not clear because

play23:21

this code is just plain JavaScript now

play23:24

we can improve this implementation and

play23:25

use typescript so we can say use

play23:28

typescript in this code

play23:37

now we have a new implementation of the

play23:40

same web server implemented using

play23:42

typescript now let's say you're a python

play23:44

developer you don't want to use

play23:46

JavaScript so here we can say generate

play23:49

this API using Python and fast API which

play23:54

is another library for building apis

play23:56

using python so

play24:03

all right now we have a new

play24:04

implementation but in this

play24:05

implementation our products are stored

play24:07

in memory again we can talk to chat GPT

play24:10

and customize this further

play24:13

all right now let's look at a few

play24:14

examples involving databases this one is

play24:16

pretty interesting so I'm going to say

play24:18

write a SQL query to generate a table

play24:22

called products with four columns note

play24:27

that I'm not specifying the column names

play24:29

and types here I'm just saying I want a

play24:31

product table with four columns see what

play24:34

happens

play24:39

now look chat GPT is smart enough to

play24:42

know that quite often products have

play24:44

attributes like ID title description and

play24:47

price if this is not what you want you

play24:50

can always specify the name and type of

play24:52

each column for example we can say write

play24:55

a SQL query to generate a table called

play24:59

products with these columns now here we

play25:03

press shift and enter so we go to the

play25:05

next line and on each line we can list a

play25:07

column we can say ID of type integer

play25:11

title of type string

play25:14

category of type integer unit price of

play25:18

type float

play25:19

and image URL of type string and you

play25:22

don't necessarily have to put a type in

play25:24

parenthesis you can type a colon and

play25:26

right after that we can specify the type

play25:28

so chat GPT doesn't have a particular

play25:30

syntax you have to follow because it can

play25:32

understand human language

play25:39

all right now in the products table we

play25:41

have columns like ID title category unit

play25:44

price and so on we can also use chat GPT

play25:47

to write queries for retrieving or

play25:50

updating data for example here we can

play25:52

say write a query to retrieve

play25:55

the top five customers in Manhattan note

play25:59

that we don't currently have a table

play26:00

called customers so we're just asking

play26:02

chatgpt to write a query to retrieve the

play26:05

top five customers in Manhattan take a

play26:08

look

play26:13

alright in this example chatgpt has

play26:16

assumed that we have a table called

play26:18

customers with these columns ID name

play26:21

address and City if our customers table

play26:23

has a different schema we need to

play26:25

specify that ahead of time so we specify

play26:27

the name and type of each column then we

play26:30

ask chat GPT to write a query to

play26:32

retrieve the top five customers now look

play26:35

at this query in this query we're simply

play26:37

selecting customers who are located in

play26:39

Manhattan so in this query the customers

play26:42

are sorted by their ID in descending

play26:44

order and the top five are returned this

play26:47

is not what we really want what we want

play26:49

is the top customers who have spent the

play26:51

most so we need to be more specific with

play26:53

our prompt so we need to tell chat CPT

play26:56

to do a join with the orders table to

play26:58

find out how much each customer has

play27:00

spent then it should grab the top 5

play27:03

customers who have spent the most so we

play27:06

can say revise this query and join the

play27:10

customers table

play27:12

with the orders table

play27:14

to find out how much each customer has

play27:17

spent then pick the top five who have

play27:22

spent the most and again here we can

play27:25

specify the schema of the orders table

play27:27

as well

play27:28

so let's go ahead

play27:34

all right look now chat GPT is assuming

play27:37

that we have two tables customers with

play27:39

these columns and orders with these

play27:41

other columns and based on this schema

play27:44

it has revised our query to retrieve the

play27:46

top five customers who have spent the

play27:48

most so that's it guys there are endless

play27:51

ways to get creative and use chat GPT I

play27:54
