hey everyone my name is vishwas and

welcome to a brand new series on node.js

for beginners

in this introductory video Let's

understand what is node.js why you might

want to learn it take a look at the

course structure and the prerequisites

to get started

let's begin

if you visit

nodejs.org which is the official site

for node.js you're going to see node.js

as an open source cross-platform

JavaScript runtime environment

now what I would like to do is break

this down into three parts

first node.js is open source which

simply means the source code for node.js

is publicly available for sharing and

modification

second

node.js is cross-platform which means it

is available for Mac windows and Linux

finally node.js is a JavaScript runtime

environment

now to understand this last part we need

a little bit of background

so let's revisit this slide after we've

understood what exactly is a JavaScript

runtime environment

for now though at a high level let me

give you a few good reasons as to why

you might want to learn node.js

node.js is a technology with which you

can build end-to-end JavaScript

applications

learn one language and you can develop

both front-end and backend for your apps

second a number of major companies like

LinkedIn Netflix PayPal have all

migrated from other backend Technologies

to node.js

third

full stack development is one of the

most sorted skill sets by companies

right now and if you are a front-end Dev

learning node.js will take you one step

closer to Landing the dream job

there is huge Community Support as well

and you can be rest assured node.js

won't be going anywhere anytime soon

it is always a good time to learn

node.js

alright now that we have an idea of what

is node.js and why you may want to learn

node.js let me briefly go over the

course structure

in the first section of the series we

will learn a few terms and Concepts that

are crucial to understanding what is

node.js

that's right an entire section just to

understand what we mean by a JavaScript

runtime environment

once we understand what is node.js we

will proceed to understand the

underlying features that are responsible

for making node.js a great technology

in section 2 we will learn about modules

in node.js

use the defined modules to be more

specific

in Section 3 we will dive deeper and

learn about the core built-in modules

that node.js ships with

this is code that you can readily use in

your application

section 4 is where it gets really

interesting

we're going to take a closer look at the

internals of node.js

a slightly Advanced topic but one that

will help you write better code

for Section 5 we will learn about npm

the node package manager which is a huge

library of third-party modules that we

can use for a variety of requirements in

our own application

npm is essential to build any medium to

large scale app with node.js

for Section 6 we will see how we can use

node.js to build a command line

interface tool

yes you can build web servers with

node.js but you can also build CLI tools

finally we will wind up the series with

a miscellaneous section where I will

cover a few topics that don't

necessarily fall under one specific

category

now you might be wondering is this all

there is to it

well about node.js itself yes these are

pretty much the Core Concepts you have

to learn

what you typically come across at work

though is building web applications

using a framework like express.js

defining API endpoints connecting to

databases adding authentication

Etc

but let me tell you to understand

express.js which is a node framework for

the web you should first know the

concepts in node.js

and express.js is a huge topic to cover

which is why I will create a separate

node.js plus express your series for

beginners in the near future

when we are done you will have a solid

understanding of both node.js and

express.js

now as far as the prerequisites are

concerned we just have one and that is

modern JavaScript

if you're new to JavaScript please watch

my crash courses on the fundamentals of

JavaScript the advanced topics in

JavaScript and also the video on the

important Concepts in es2015 and above

a link should be in the description down

below

all right if this is clear let's proceed

to the first section where we will learn

about a few important topics that lay

the foundation to understand what

exactly is node.js

I'll see you in the next one
