JAVA

JavaScript (JS) is a dynamic computer programming language. It is most commonly used as part of web browsers, whose implementations allow client-side scripts to interact with  the user, control the browser, communicate asynchronously, and alter the document content that is displayed. It is also being used in server-side programming, game development and the creation   of desktop and mobile applications. The application of JavaScript to use outside of web pages—for example, in PDF documents, site-specific browsers, and desktop widgets—is also significant. Newer and faster JavaScript VMs and platforms built upon them (notably Node.js) have also increased the popularity of JavaScript for server-side web applications. On the client side, JavaScript was traditionally imple-mented as an interpreted language but just-in-time compilation is now performed by recent (post-2012) browsers.

 Originally developed by Brendan Eich and known as LiveScript, which was renamed to JavaScript in 1995. JavaScript is an interpreted   client-side scripting language that allows a web designer the ability to insert code into their web page. JavaScript is commonly placed into an HTML, ASP, or a similar file and run directly from the web page to perform tasks such as printing the time and date, creating a calendar,  or other tasks that are not possible through plain HTML.
