What is JavaScript?

This is a dynamic programmed language used in computers. It is mostly used in web pages which allow client-user interaction. It can be referred to as a computer programming language interpreted with various object-oriented capabilities.

JavaScript was implemented in 1995. Initially, it was known as LiveScript, but later Netscape changed the name to JavaScript. It is mostly used in internet explorer, Netscape, and other browsers. The main purpose of JavaScript is to give the user a better experience. It achieves this by manipulates various objects in the HTML document. Both the HTML and the objects work collectively to form a Document Object Model (DOM); Hyper HTML Vs VDOM .

Client-Side JavaScript

This is the main form of the language. In JavaScript, the domain name should be referenced or included by HTML document for easy interpretation in the browser. The web page should not be static but can include the programs that interact perfectly well with the particular browser in use.
The client-side JavaScript mechanism is more beneficial than the traditional CGI scripts. For instance, unlike when using the conventional server side, you can easily confirm if the email is valid or not. Usually, the JavaScript code is only executed and submitted to the server just if the details in the form submitted are accurate.

Benefits Of JavaScript

  • JavaScript can create new functions in the script. A function keyword is consequently used to declare a function

 Why Do I Need JavaScript?
