JavaScript, abbreviated as JS, is an interpreted programming language that can update both HTML and CSS, and can calculate, manipulate and validate data.

JavaScript is the most widely used scripting language in the world. JavaScript is one of the core technologies on the World Wide Web, alongside HTML and CSS. An estimated 95% of websites use JavaScript. All major web browsers have a built-in JavaScript engine which renders the code on user’s devices.

JavaScript has built in features called ‘functions’. The biggest advantage of JavaScript is the ability to produce the same result on all modern browsers.

JavaScript’s official name is ECMAScript and is defined under Standard ECMA-262. The most frequently used JavaScript Frameworks are React JS, Angular JS, Create JS and jQuery.
