Java Script is one of the most popular scripting language on the web. The support for executing Java Script code exists (full or partial) in all major web browsers, including Internet Explorer, Opera, Firefox, Chrome and Safari. 

The Java Script programming language is a scripting language we use to develop scripts running in the web browser. Java Script was invented during the 90's as a scripting language supported by the Netscape Navigator browser. At a later stage it was adopted by Microsoft and was renamed as JScript. Though there are some similarities between Java and JavaScript the two programming languages are different in their nature. While the Java programming language requires us to compile our code before we execute it, when writing a Java Script code there is no need to compile it. The Java Script code is interpreted by the browser running environment. During the years two variations of Java Script (JScript on the one hand and Java Script on the other) have evolved differently. The ECMA Script is a formal specification that defines the core part of the language and refers to syntax, types, statements, keywords, reserved words, operators and objects only. Given the various differences we find when comparing different web browsers' support for Java Script, coding in Java Script might become a complex task that involves with checking the exact browser on which the script is running. This complexity has led during the last years to the evolvement of various Java Script libraries we can freely use on our end.
