Hello everyone,

In this blog, we will discuss how and where Javascript is used in the industry.

Before we get started with our main topic, we should know what JavaScript is.

JavaScript != Java

JavaScript is a scripting or programming language that allows us to provide the functionality to our webpage. It enables us to create dynamically updating content.

JavaScript is mainly used for web-based applications and web browsers. But it goes beyond the web in software, servers, and embedded hardware controls

Characteristic of JavaScript

  • Object-Oriented Scripting Language
  • Client edge Technology
  • Validation of user's input
  • Interpreter centered
  • Lightweight and delicate
  • Handling events

Advantages of JavaScript

  • Speed
  • Simplicity
  • Popularity
  • Server Load

Disadvantage of JavaScript

  • Client-Side Security
  • Browser support

LinkedIn is by far the most popular professional social media and networking website in the world. With more than 600 million members located throughout the world, the platform helps white-collar workers develop a professional network and search for career opportunities

LinkedIn uses Javascript, which increased the performance of LinkedIn. LinkedIn uses Node.js for its application development.

  • Uber

The mobile ride-sharing company Uber has grown in leaps and bounds since it was founded in 2009. While the company initially launched with limited transportation services in San Francisco proper only, its services are now available in 173 countries across the globe.

Uber uses Node.js for their application and they use it for the following reasons:

  • It can process a huge amount of information quickly.
  • It is perfect for rapid interaction
  • Improvements are made continually and ensures that the language involves with the user end.
  • Facebook

Facebook uses a JavaScript development library. The most popular Javascript framework React Native was developed by Facebook.

React Native was created to solve a major problem with Facebook’s mobile applications. Cross-platform development allows companies to develop mobile applications that function on multiple operating systems.

Facebook created React Native to overcome the use design challenge. The deployment of native applications has improved Facebook’s user experience. Real-time events on the user dashboard now load twice as quickly and the app has fewer bugs than before. Just as importantly, Facebook’s users love their new native apps and improved user experience.

  • Netflix

Netflix uses Node.js as it solved the problem of Netflix developers using two different languages as one for the front end and one for the backend.

By using the same JavaScript framework on the front-end and back-end, developers reduced their workload and increased the quality of the final web application. By utilizing separate APIs written in Node.js, Netflix was able to reduce its total development time and improve its application’s speed.

So that's how JavaScript solved many industry use cases and became a powerful language.
