Applications of JavaScript

The applications of JavaScript have expanded a lot over the past decade. A few of them are listed below.

• Dynamic webpages: It promotes dynamic interaction between the user and the webpage. For example, the user can now load new content (either an image or an object) without refreshing the window.
• Web and App Development: The libraries and frameworks present in JavaScript are well suited to develop a web page and/or an application.
• Game Development: 2 Dimensional and even 3 Dimensional games can be developed with the help of frameworks and libraries offered by JavaScript.
• Building Servers: Apart from web and application development, the user can build web servers and work on back-end development as well.

Advantages of Enabling JavaScript in Your Browser

1. The user interactivity is increased in web pages.
2. The user can access several interactive web pages once JavaScript is enabled in the browser.
3. The time required to establish a connection between the server and the system is reduced since JavaScript works on the client side.
4. When JavaScript is enabled, the bandwidth and the load are considerably reduced.

Drawbacks of Enabling JavaScript in Your Browser

1. The implementation of JavaScript cannot be carried out with the help of a single-parent body.
