“Nobody expected this, but JavaScript has become the world’s most important programming language today” —Douglas Crockford, JavaScript Architect at PayPal

What is Javascript?

JavaScript is a simple and easy-to-learn programming language as compared to other languages such as C++, Ruby, and Python. It is a high-level, interpreted language that can easily be embedded with languages like HTML. It was developed by Netscape Communications Corporation, Mozilla Foundation, and ECMA International. Brendan Eich is known as the creator or designer of the JavaScript programming language.

Initially, JavaScript was known as LiveScript, but later Netscape changed its name to

JavaScript. Some amazing features of JavaScript are as follows:

  • Lightweight, interpreted language.
  • Easily embedded with languages like HTML, CSS, and Java.
  • Also works as a client-side scripting language, which helps in creating dynamic web pages.

JavaScript is an open source and cross-platform language and therefore mostly used for creating network-centric applications. Nowadays it has become an inseparable part of the core technologies of the internet. JavaScript is used in web technologies to make web pages interactive. Along with HTML and CSS, JavaScript is widely used in web servers and databases. Hence its wide popularity among these kinds of websites.

In order to begin with JavaScript, you can use any simple text editor such as Notepad.
