This document discusses and compares popular JavaScript frameworks including React, Angular, Vue, and Node.js. It provides brief descriptions of each framework, highlighting what they are used for and some top brands that use each one. React is a library for building user interfaces, Angular is a full-stack framework created by Google, Vue is an open-source framework for building interfaces, and Node.js is a runtime environment that executes JavaScript outside browsers.

1. Top Javascript Frameworks
A JavaScript framework is an application framework
written in JavaScript. It differs from a JavaScript library
in its control flow: a library offers functions to be called
by its parent code, whereas a framework defines the
entire application design.
We will explore the few of them that includes:
1) React
2) Angular
3) Vue
4) Node.Js

2. React

React is a JavaScript library for building user
interfaces.

It is created by Facebook and community of
individual developers and companies in May 2013.

This framework is developed with the purpose of
“building large applications with data that
changes again and again over time”

3. Reasons to choose React in your project

It's awesome for SEO : You can able to run React.js
on the server and the virtual DOM will be returned
and rendered to the browser as a regular web page.
The virtual DOM (VDOM) is a programming concept
where an ideal, or “virtual”, representation of a UI is
kept in memory and synced with the “real” DOM by a
library such as ReactDOM.

The JavaScript Library : React.js is using JSX tag
syntax. JSX is an XML/HTML-like syntax used by
React that extends ECMAScript so that XML/HTML-
like text can co-exist with JavaScript/React code. You
can read more at
https://reactjs.org/docs/introducing-jsx.html

4. Reasons to choose React in your project

Debugging is very easy: The chrome extension of
React.js makes debugging very easy for your app. It
will allows you to directly check the virtual dom.

Reusable React Components

List of Top Brands use React Js: Twitter,
WordPress, New York Times, Airbnb, Yahoo, Netflix,
and Uber etc..

5. Angular

Angular is a Typescript-based open source full-stack
web application framework.

It is created by Google and by community of
individuals and corporations in September 2016.

Angular is a complete rewrite from the same team
that built AngularJS.

6. Reasons to choose angular in your project

MVC Framework

Uses HTML as a template language

Dependency handling

Two way data binding

Support from Google and large community

Modularize your application with lazy loading your
modules

List of Top Brands use Angular: PayPal, Upwork,
Google, Nike, HBO, Sony etc...

7. Vue.js

Vue.js(commonly referred as vue) is an open source
JavaScript framework for building user interfaces and
single page applications.

Vue was created by “Evan You (Software
Developer)” after working from Google using
AngularJs in a number of projects, in February 2014.

The thought of “Evan You” while building vue was “I
figured, what if I extract the part that I really liked
about Angular and build something really light.”

8. Reasons to choose vue in your project

No build step required. It is easy to get started.

Friendly learning curve and well documented

Very small size (18-21kb)

Two way data binding

Uses HTML as a template language

Uses virtual Dom

Debugging very easy by adding Google chrome
extension “Vue Devtools”. It will directly check your
virtual Dom.

Top Brands use Vue: Alibaba, Xiaomi, Gitlab,
Expedia, Laracasts etc...

9. Node.js

Node.js is an open source, cross platform JavaScript
run-time environment that executes JavaScript code
outside of a browser.

Node is a runtime environment and not a framework.

Node.js has an even-driven architecture capable of
asynchronous I/O operations.

Node.js was originally wriiten by Ryan Dahl in 2009.

The biggest difference between Node.js and PHP is
that most functions in PHP block the execution until
completion, while Node.js functions are non-blocking.

10. Node.js Framework List :

It is also good fit for the projects that need event-
based servers as well as non-blocking driven
servers.

It is quite fast: It uses V8 engine by Google.

Node.js serves as a proxy server MySQL.

Code executes faster compare to other frameworks.

Top Brands use Node.js: Netflix, Linkedin, Trello,
Uber, PayPal, eBay, NASA etc...
