JavaScript is what is known as a client-side script. Most Web applications, such as a search engine, work because of an interaction between the user’s device and a remote server. The software on the remote server sends information to the client and the software on the client side reads the information and renders a Web page on screen.

An HTML page is a static one and without JavaScript it would be static still. JavaScript can make the website more interactive and user- friendliness of JavaScript helps easy navigation of the website and helps designers to guide the visitors with additional information or guide them through walkthroughs. Visual effects can also be achieved with JavaScript. JavaScript can be used effectively to create special effects like rollover for images.

While JavaScript is not the only client-side scripting language on the Internet, it was one of the first and it is still the most widely used.

A client-side script is a programming language that performs its tasks entirely on the client’s machine and does not need to interact with the server to function. For instance, if you have a Web page loaded on your computer and your Internet service provider goes down, you are still able to interact with the Web pages already loaded on your browser. You will not, however, be able to navigate to new Web pages or access any data located remotely.

Any organization that has to deal with dynamic website and website is bound to use javascript in it’s tech stack.

This means that almost every organization deals with javascript on a regular basis

The frameworks of javascript

Javascript has various frameworks to support the frontend as well as backend framework. This is a very important fact because in the 21st century no ones want to wait and to create a web application from scratch is not something that attracts organizations

Angular

One of the most powerful, efficient, and open-source JavaScript frameworks is Angular. Google operates this framework and is implemented to use for developing a Single Page Application (SPA). It extends the HTML into the application and interprets the attributes to perform data binding.

React

Created by Facebook, the React framework has earned popularity within a short period. It is used to develop and operate the dynamic User Interface of the web pages with high incoming traffic. It makes the use of a virtual DOM, and hence, the integration of the same with any application is more straightforward.

Vue.js

Though developed in the year 2016, this JavaScript framework has already made its way into the market and has proven its worth by offering various features. Its dual integration mode is one of the most attractive features for creating high-end SPA or Single Page Application. It is a much reliable platform for developing cross-platform.

Ember.js

The introduction of Ember.js to the software market was 2015, and since then, it has gained popularity with its wide application area. The features of Ember.js support two-way data binding and hence, establish a reliable platform for handling the complicated User Interfaces. Popular websites like LinkedIn, Netflix, Nordstrom, and many more use the Ember.JS platform for their websites.

There are various other frameworks that are popular but the list is very long so I have mentioned the few of the most popular.

Industry Use case:

Facebook

You’re probably aware that Facebook uses JavaScript. It’s kind of hard to miss. What’s probably not as obvious is exactly how much JavaScript goes into making Facebook and how much Facebook is involved in JavaScript development.

Try disabling JavaScript in your web browser and going to Facebook. The website will actually stop you from logging in because it won’t work without JavaScript.

You may have noticed the way that Facebook loads. Each piece of the page is separate. Facebook has invented its own way of breaking down and delivering sections of JavaScript separately. In an odd way, each section of your Facebook page is a collection of independent JavaScript applications.

It doesn’t stop there. Facebook created React, one of the most popular front end frameworks. Facebook uses React on Facebook.com as well as Instagram and WhatsApp.
