Industry Use-Cases of JavaScript
What is JavaScript ?
JavaScript is a dynamic programming language that’s used for web development, in web applications, for game development, and lots more. It allows you to implement dynamic features on web pages that cannot be done with only HTML and CSS.
Uses of JavaScript
1. Web Development
JavaScript is a client scripting language that is used for creating web pages. It is a standalone language developed in Netscape. It is used when a webpage is to be made dynamic and add special effects on pages like rollover, roll out and many types of graphics. It is mostly used by all websites for validation. In addition to validations, it supports external applications like PDF documents, running widgets, supporting flash applications, etc. It can also load content into a document whenever the user requires it without even reloading the entire page.
2. Server Applications
Node JS is built on Chrome’s Javascript runtime for building fast and scalable network applications. It uses event-driven, lightweight, and efficient applications which are to be distributed over the systems with the help of a server. Javascript is used to handle HTTP requests and generate content. When a user is writing thick applications in JavaScript on the client then a user may even write the logic in JavaScript on the server so that cognitive leaps can be done from one language to the other.
Advantages of JS
- Regardless of where you host JavaScript, it always gets executed on client environment to save lots of a bandwidth and make execution process fast.
- In JavaScript, XMLHttpRequest is an important object that was designed by Microsoft. The object call made by XMLHttpRequest as a asynchronous HTTP request to the server to tranfser the data to both sides without reloading the page
- The biggest advantage to JavaScript having a ability to support all modern browsers and produce an equivalent result.
- Global companies support community development by creating projects that are important. An example is Google (created Angular framework) or Facebook (created the React.js framework).
- JavaScript is employed everywhere on the web .
