in this tutorial you're going to learn
all about what chat GPT is how it works
and most importantly how you can use it
to boost your productivity as a software
developer as a seasoned developer and
teacher let me tell you chat GPT is a
game changer you don't want to miss out
on don't take my word for it just watch
this video and see for yourself
[Music]
my name is mosh hamadani and I'm super
excited to be bringing you this tutorial
on chat GPT I've helped millions of
people learn to code and become
professional software Engineers through
this Channel and my online school
codewithmash.com if you are new here
make sure to subscribe so you never miss
a video
so what exactly is chat GPT and how does
it work chat jpt is a Cutting Edge AI
tool created by open AI it was released
in November 2022 and gained 1 million
users in just 5 days in comparison it
took Netflix three and a half years and
Instagram two and a half months to get
the same number of users chat gbt is an
advanced language model that can
understand and generate text you can use
it to create content for your website
write articles emails tweets cover
letters and so on you can also use it to
generate code in a number of different
programming languages like python
JavaScript HTML CSS and much much more
you can use it to generate dummy data
write unit tests translate text or code
from one language to another you can use
it to explain code for example if there
is a piece of code you don't understand
you can ask it and it will explain to
you like a patient teacher but I have to
be honest sometimes it explains too much
chat GPT can also help you learn and
remember things faster for example you
can give it some text and have it ask
you a bunch of questions it can also
prepare you for job interviews you can
have it improve your resume write a
cover letter for you and also interview
you like an interviewer now do you think
chat GPT is going to take your job let
me know in the comments below the
reality is whether you like it or not
chat GPT is here to stay in this
tutorial I'm going to show you how to
use it to get more creative and get
things done a lot faster I'll be showing
you various examples for different
programming languages both for beginners
and experienced developers but before we
dive into that let's take a moment and
understand how chat gbt works chat GPT
uses a type of artificial intelligence
called a language model a language model
is a type of software that is designed
to understand and generate human
language it does this by looking at a
large amount of Text data and learning
the patterns and rules of a language for
example if the language model is trained
on a lot of English texts it will learn
about the grammar and structure of
English as well as the meanings of words
and how they are used in different
contexts once the language model has
learned about a language it can then be
used to generate text in that language
now chat GPT provides different language
models for different purposes gpt3
models which are designed to understand
and generate natural language like
English and codecs which are
specifically trained to understand and
generate code these models are trained
on billions of lines of code publicly
available on GitHub they're mostly
capable in Python but they're also
pretty good in a bunch of other
languages like HTML CSS says JavaScript
typescript Ruby SQL and more now before
we look at specific examples remember
shot GPT like any tool has limitations
it might sometimes generate incorrect
harmful or biased information so don't
take whatever it tells you as a silver
bullet don't use it to learn to code
because the code that is generated is
not guaranteed to be right it might be
functional but it might not be the best
way to code so in a nutshell chatgpt is
a powerful tool that can help you be
more creative and efficient but it's not
a substitute for human expertise and
judgment so that's the theory part now
let's move on and see chat GPT in action
so head over to
chat.openai.com if you don't have an
account sign up it takes only a minute
once you have logged in you're going to
see the main screen with an input box to
talk to chat GPT there is also a Chrome
extension and a desktop application
available if you don't want to use the
web interface I'll put the links down
below this video alright now let's get
to the fun part going forward I'll be
showing you various use cases for
different programming languages we'll
start off with some general purpose
questions that apply to anyone
regardless of the programming languages
and tools they use you will see how you
can use chat GPT to learn new things
write shell scripts get commands start a
business write legal documents and so on
once we cover the basics then we'll dive
into specific examples for front-end
back-end and database development I will
show you examples using HTML CSS
JavaScript typescript python SQL and
more
now here's my first question what are
the top three books for learning Java
all right as you can see chat GPT has
given us a very comprehensive and
detailed answer now here we can ask more
detailed questions for example we can
ask questions about the first book so we
can ask what are the key takeaways from
head first Java
all right another comprehensive answer
you can see that this book teaches you
about object-oriented programming Java
fundamentals threading and concurrency
GUI programming and so on now we can
also ask more general questions like how
do I become a front-end developer
so now chat GPT is saying that to become
a front-end developer you need to know
the basics of HTML CSS and JavaScript
you should practice building websites
then you should learn a front-end
framework like react angular View and so
on you should also know about Version
Control Systems like git GitHub and Swap
this is pretty much the same answer you
will find on every website that gives
you a roadmap to become a front-end
developer
now let's look at more specific examples
we can ask chatgpt to write a shell
command for us for example we can say
write a bash command to find the name of
all JPEG files in the directory and
write them all to a text file
take a look
I love this answer so if you're not good
with Linux commands you can easily find
the final instruction you should use to
solve that problem but what is beautiful
about chatgpt is that it also explains
how this command Works line by line
piece by piece we can also have chat GPT
red git commands for us for example we
can ask how do I know
how many lines of code
I've committed to a git Repository
we can also use chat GPT to get creative
for example let's say you want to start
a business you can have chat GPT
generate app or website names for you
for example we can say I want to make a
revolutionary online shopping app give
me some good app names
so chatgpt is suggesting names like shop
is Swift cart streamline and so on I
think this list is pretty damn good now
these are just some example prompt you
don't need to use the exact same wording
to talk to chat GPT you can ask any
questions you want in your own way now
if you have used this tool before let us
know in the comments below the
interesting questions you have asked so
we can all learn and Inspire each other
we can also ask chat GPT to write
contracts for us here's an example I
want to hire a graphic designer to
design a website
we have agreed
that they will deliver the first draft
in two weeks and offer three iterations
free of charge
any iteration after will be charged
at fifty dollars an hour write a
contract for us so the more details we
give to chat GPT the better response
we'll get
all right take a look
this is a pretty damn good contract to
start with of course you don't want to
take this as is and use it in the real
world without first passing it by a real
lawyer that's why earlier I told you
that chat CPT is not a replacement for
humans at least none at the moment it's
just a way to increase your productivity
and get things done in less time
now if you're applying for a job there
are a number of ways chat GPT can help
you for example you can have it write a
resume for you hear me can say I have
three years of experience coding in HTML
CSS and JavaScript
write a resume for me of course we can
give it more details we can explain our
education level our past projects and so
on but look at what we get with this
simple prompt
all right take a look
so chat GPT created a basic layout
that includes our name address phone
number email some objective summary
technical skills and it has already
listed all the related web Technologies
so we have HTML CSS JavaScript jQuery
bootstrap we didn't mention any of this
but it assumed that we have these skills
it also included a section about
professional experience including past
projects as well as education
certifications and so on again it's a
great starting point now let's say
you're applying for a front-end
developer role you can ask chatgpt to
write a cover letter for you that you
can email to that company so we can say
applying for a front and engineer role
at some company
write a cover letter for me
all right take a look
we have a comprehensive cover letter
beautifully written in perfect English
how good is that now let me show you
another fun one you can have chat GPT
ask you interview questions we can say
act as a technical interviewer and ask
me five questions about JavaScript
take a look
all right so here we have five questions
that are often asked in technical
interviews now let's say you don't know
the answer to the first question you can
ask a follow-up question so the beauty
of chat GPT is that it remembers
everything you have told it in this
conversation thread so here we can say
what is the answer to the first question
again we get a very comprehensive
detailed answer you can also ask chat
GPT to help you write emails for example
we can say write an email to my boss
asking for a raise
I've worked at this company
for two years and successfully
delivered several projects
on time
seriously if I wanted to write this
myself it would take me 10 to 15 minutes
if not longer I got the answer in just
two seconds
all right now let's look at a few
examples involving code we'll start with
using python for writing a command line
tool we can say write a python function
for generating a random password
so as you can see we get a piece of code
beautifully highlighted with explanation
of how it works now if there's a part of
this code that you don't understand you
can always ask follow-up questions for
example we can ask what this expression
does in this code so we can ask what
does
4 in I range of length 2 in this code
take a look
really really useful couldn't be better
now we can also ask computer science
questions like what is the time
complexity of this function
now if you're not familiar with this
concept time complexity is a way to
explain how large inputs impact the
performance of an algorithm it's really
beyond the scope of this tutorial I've
covered it in detail in my data
structures course in case you're
interested so let's see what we get
so chat GPT is saying that this
function's time complexity is linear now
let's take this to the next level we can
ask chatgpt to write unit tests for this
function so write unit tests for this
function
seriously how good is this if I wanted
to write all this unit tests by hand it
would take me probably 20 to 30 minutes
if not longer of course we should always
use our own judgment to make sure that
the tests are correct but I think this
code is a great starting point and it
really saves us a lot of time
we can also ask chat GPT for ideas to
improve our code for example here on
w3schools.com we have this piece of
python code where we use a for Loop to
iterate over a list of fruits if the
fruit has a in it then we add it to a
new list I'm going to copy this code and
give it to chat GPT to see how we can
improve this code so take a look
how can I improve this code now here we
should hold shift and then press enter
so we go to the next line now we paste
our code and then press enter to submit
the question
all right look a lot of details
absolutely amazing one thing I love here
is that chat apt is suggesting to use a
list comprehension which is a one-liner
for implementing the same logic of
course there are more ways to improve
this code we are not going to get into
details here
we can also ask chat jpt to convert our
code from one language to another for
example we can say convert this python
code to JavaScript
foreign
just a few seconds our code was
converted to JavaScript and down below
we have all the details about how this
code works
we can also use chat CPT to generate
dummy data for example we can say
generate dummy data for a table called
customers each customer should have an
ID
first name last name and City
now in this case chat GPT gave us a
python script for generating dummy data
but what if we want the actual data not
a python script we can say I don't need
a python script just give me the data
so now we get a list of 10 people
represented using the Json format now we
can take this to the next level and say
create a python class for storing these
objects
foreign
look we get an example of a python class
called customer
along with how we can use this class to
store a bunch of customer objects inside
the list absolutely beautiful
now if you're a front-end developer you
can ask chat jpt to generate some HTML
markup for you and this is where
examples get more and more interesting
for example we can say write the HTML
and CSS code for displaying a card
foreign
take a look we have the markup here we
have a div with the class of card inside
the div we have an image then we have
the card content inside this div we have
the card title and cart description
really really good and right below that
we have all the CSS we need
to display a beautiful card of course we
probably need to customize this but
again this is a great starting point now
we can stop here or we can customize
this further for example we can say add
a button below the card content
foreign
look what happened so now we have a new
markup right under the card description
we have a new div with the class of card
action and inside this div we have a
button beautiful now we also have more
styles for this button we have the plane
Styles as well as the styles for the
hover effect now let's take this to the
next level we can say when I hover my
mouse over the card
I want the card to slightly slide up
so charge if it is suggesting that we
should use the hover sudo class and the
translate function Translate Y to slide
the card up beautiful I love it it's
also suggesting an alternative solution
using box Shadow so it's pretty up to
speed with CSS features now let me show
you something really cool we can ask
chat GPT to rewrite this code using
Tailwind CSS if you're not familiar with
Tailwind it's a CSS library that has
gained a lot of popularity lately so
here we can say can you rewrite this
code using Tailwind CSS
foreign
there you go now we have the same markup
but with the utilityclasses that come
with Tailwind CSS so we don't have to
create CSS classes anymore now here we
can get more creative and see what other
UI libraries are supported
next we can bring some JavaScript to the
mix and make this interactive so we can
say when I click on the button
send an HTTP request to slash API slash
products
foreign
let's look at the generated code so chat
GPT is suggesting to use the fetch API
that is supported in pretty much most
modern browsers but I personally don't
like to use the fetch API so I'm going
to customize this further and say
instead of the fetch API use axis which
is a library for sending HTTP requests
now take a look
all right now we have the instructions
for installing axios using npm or yarn
as well as a modified example using axis
beautiful
we can also ask chat GPT to help us with
compile time or runtime errors here is
an example let's say as part of writing
some JavaScript code we got an error
saying uncut type error cannot read
property let's say bar of undefined
anyone who has written a little bit of
JavaScript code has probably come across
this error so we can copy paste the
error message here
now chat GPT explains exactly what this
error is and how we can potentially
solve it
so going forward I think a lot of people
will start to use chat GPT instead of
now we can also throw react here and
make the example more interesting so we
can say create a react component for
displaying a card
all right let's see what's happening
here so up here we have an example of a
function component for displaying a card
now I personally don't like to have a
parameter called props it would be nicer
to destructure this parameter and grab
individual properties like title
description and so on so if you're not
familiar with this concept don't worry
just continue watching we're not going
to do a lot of fancy JavaScript stuff in
this video this is just to open your
eyes to the possibilities so let's take
this to the next level and say this
structure the props parameter so the
beautiful thing about chat GPT is that
it remembers our conversations so let's
go ahead
foreign
we have a new implementation of the card
component with the props parameter
destructured
all right now let's move on and look at
a few examples involving back-end
development for example we can ask chat
jpt to build an API for us with node and
express so here we can say I need an API
built with
express.js to return the list of
products
each product should have attributes like
ID title description price and image URL
thank you
all right look at this implementation in
this implementation we have an area of
products stored in memory and we have an
API endpoint exposed at this URL I don't
want to have an area of products in
memory I want this product to be stored
in a mongodb database so here we can say
modify the code and retrieve the
products
from a mongodb or a MySQL or a postgres
whatever database
now we get a new implementation where
products are retrieved from a mongodb
database using the Mongoose Library
here it is
now in this implementation the type of
these parameters is not clear because
this code is just plain JavaScript now
we can improve this implementation and
use typescript so we can say use
typescript in this code
now we have a new implementation of the
same web server implemented using
typescript now let's say you're a python
developer you don't want to use
JavaScript so here we can say generate
this API using Python and fast API which
is another library for building apis
using python so
all right now we have a new
implementation but in this
implementation our products are stored
in memory again we can talk to chat GPT
and customize this further
all right now let's look at a few
examples involving databases this one is
pretty interesting so I'm going to say
write a SQL query to generate a table
called products with four columns note
that I'm not specifying the column names
and types here I'm just saying I want a
product table with four columns see what
happens
now look chat GPT is smart enough to
know that quite often products have
attributes like ID title description and
price if this is not what you want you
can always specify the name and type of
each column for example we can say write
a SQL query to generate a table called
products with these columns now here we
press shift and enter so we go to the
next line and on each line we can list a
column we can say ID of type integer
title of type string
category of type integer unit price of
type float
and image URL of type string and you
don't necessarily have to put a type in
parenthesis you can type a colon and
right after that we can specify the type
so chat GPT doesn't have a particular
syntax you have to follow because it can
understand human language
all right now in the products table we
have columns like ID title category unit
price and so on we can also use chat GPT
to write queries for retrieving or
updating data for example here we can
say write a query to retrieve
the top five customers in Manhattan note
that we don't currently have a table
called customers so we're just asking
chatgpt to write a query to retrieve the
top five customers in Manhattan take a
look
alright in this example chatgpt has
assumed that we have a table called
customers with these columns ID name
address and City if our customers table
has a different schema we need to
specify that ahead of time so we specify
the name and type of each column then we
ask chat GPT to write a query to
retrieve the top five customers now look
at this query in this query we're simply
selecting customers who are located in
Manhattan so in this query the customers
are sorted by their ID in descending
order and the top five are returned this
is not what we really want what we want
is the top customers who have spent the
most so we need to be more specific with
our prompt so we need to tell chat CPT
to do a join with the orders table to
find out how much each customer has
spent then it should grab the top 5
customers who have spent the most so we
can say revise this query and join the
customers table
with the orders table
to find out how much each customer has
spent then pick the top five who have
spent the most and again here we can
specify the schema of the orders table
as well
so let's go ahead
all right look now chat GPT is assuming
that we have two tables customers with
these columns and orders with these
other columns and based on this schema
it has revised our query to retrieve the
top five customers who have spent the
most so that's it guys there are endless
ways to get creative and use chat GPT I
