What is Javascript
Javascript is a scripting language(supports scripts) for Web pages but it is also used in non-browser environments as well. It is a powerful, lightweight, interpreted, scripting language with first-class functions (i.e. the language supports passing functions as arguments to other functions).
In order to add the dynamic interactivity to web pages Javascript is embedded within Hypertext Markup Language (HTML). Since it runs on the client-side of the web so it can be used to design/program how the web pages behave on the occurrence of a particular event. That's the reason why it is widely used for the behavior of the web pages.
