What is JavaScript(JS)? JavaScript is a lightweight, interpreted programming language with object-oriented capabilities that allows you to build interactivity into otherwise static HTML pages. It was developed by Brendan Eich in 1995 to give web pages a little more pep than the <blink> tag could provide. Today it has far more powerful uses and companies like Google and Facebook use JavaScript to build complex desktop-like web applications. With the launch of Node.js, It has also become one of the most popular languages for building server-side software. Today, even the web isn’t big enough to contain JavaScript’s versatility. The general-purpose core of the language has been embedded in Netscape, Internet Explorer, and other web browsers.
