Advantages of JavaScript

JavaScript is a popular coding language that is often used alongside the HTML language in website development. These scripts help to make a website more interactive for the users and offer more flexibility for the Web designers. It is also an inexpensive language to program and implement into Web design projects. Because of the many advantages in using JavaScript, a number of popular websites and online games employ these scripts to enhance their visitors' online experience.


The biggest advantage of JavaScript is the interactivity it can provide to your website. JavaScript is a flexible language that can be used in coding small interactions, such as drop- down menus and webpage text effects, as well as large interactions, such as full JavaScript chat rooms or interactive games. These effects can provide more efficient Web design and navigation, make a webpage more memorable or offer visitors entertainment that will keep them returning to your website.


Website users do not need special software or downloads to view JavaScript. Most major Internet browsers, such as Internet Explorer, Firefox and Chrome, have built-in JavaScript capabilities. While not every script will always look exactly the same in each browser, basic JavaScript does have cross-browser support. This allows visitors to experience the interactivity of the website no matter which Internet browser they choose to use. Users can also choose to turn on and off JavaScript code on their browser if the effects bother them for any reason.

Client-Side Processing

JavaScript is quick to load and execute from web pages because the Internet browser is the client that does all of the processing work. Rather than having to wait for a Web server to reply to each JavaScript demand, the Internet browser downloads and launches the JavaScript on its own. This also allows some JavaScripts to launch in saved web pages, even if the computer is not connected to the Internet.


While JavaScript is a coding language that takes time and effort to learn, it is an inexpensive language in which to code. JavaScript does not require any special compilers or editors with which to work. You can code JavaScript directly into a text editor such as Notepad or Wordpad. You can also code your JavaScript straight into your website's HTML code and upload it to the Internet without specialised software to launch the script.
