JavaScript

Add visual effect and interactivity to apps, build responsive website, web and cross-platform mobile apps and games, or server applications

What is JavaScript?

JavaScript is a client-side scripting language. It is also one of the simplest, most versatile and effective programing languages. Mainly, it is used to extend the functionalities in websites and make web pages more interactive to the users. According to recent surveys, it is the most popular programing language in the world. Due to its nature, JavaScript works on a large number of platforms and devices, including IoT (Internet of Things) devices.

What is JavaScript Used For?

The uses of JavaScript range from on-screen visual effects to processing and calculating data on web pages, as well as adding extended functionality to websites using third-party scripts. It is multi-purpose and flexible, finding its way into many development projects.

JavaScript is supported by many libraries that make it easier to use, and allow developers to use the language for building:

Responsive Websites

One of the most common uses of JavaScript is adding interactivity and behavior to websites. Also, it is used for adding responsiveness and enhancing user experience.

Web Applications

Robust web applications are another thing you can build by using JavaScript. It works in the background of some of the most famous web applications like Google Maps, allowing users to zoom in on an area and see more details.

Server Applications

Few years ago, with the introduction of NodeJS, JavaScript made its way from browser to server. Now, major companies such as Wal-Mart use it as a key part of their back-end infrastructure.

Games

Traditionally, browsers are not a games platform, but recently, they have become a robust venue for games. The addition of a new HTML5 element โ€“ canvas, the level of complexity possible in browser-based games has increased exponentially, enabling the use of JavaScript code for game development.

Cross-platform Mobile Apps

JavaScript has one very powerful use โ€“ building mobile apps. Thanks to React Native, you can now bridge the gap between Android and iOS apps, and develop cross-platform mobile apps. Many popular apps like Facebook, Instagram, Airbnb, Skype, Tesla, F8, Bloomberg, are using React Native.

Advantages of Using JavaScript

The versatile nature of JavaScript is evident in its presence everywhere โ€“ in browsers, in servers, in performance native apps, cross-platform desktop apps, in powering smart TVs, and much more. The reason for this lies in the many advantages JavaScript offers to developers and end-users as well.

Improved Interactivity and Functionality of Apps

JavaScript executed on the client-side is used for adding interactive features and functionalities to apps that make them more dynamic and easier to use for the end-user. It has a variety of libraries and frameworks that speed up development and time to market.

Full Browser Support

All modern browsers have a built-in capability to support JavaScript. That increases the functionality of web apps and pages, saving development time.

Multi-Functionality and Speed

Similarly, the rich functionality of the language enables both, client-side and server-side development which supports building easy-sustainable products. It executes very fast, and it is supported by numerous frameworks, libraries, plugins, and tools which ensure continuous, long-term support.

Interoperability

JavaScript is not only easy to use on its own, but it also works together with other programing languages because it is compatible with most server-side technologies, such as Java, Ruby, Python, PHP, etc.
