Javascript is a programming language.
You can do anything with it that you can do with other programming languages.
As with other languages, you need a text editor and a compiler/interpreter in order to develop with it.
It is mostly used with websites to provide better interaction than HTML can do alone and most web browsers have a built in interpreter for javascript. For security reasons, javascript in the browser is limited (so it can't directly access the filesystem, for example).
See this list of resources for further learning.
Javascript is a programming language used, in context of web sites, to implement behavior function to a page on client side. Using HTML and CSS only, with no Javascript, you can only show things in a pre-defined way. With Javascript, you can control the way things behave.
You can use whatever text editor you like to write Javascript code, and a web browser to run it.
JavaScript is well-suited for performing task within a web browser.It is primarily used to interact with users. With JavaScript you can do:
- it can change HTML content, HTML styles, HTML attributes.
- it can detect what browser a person is using and customize the webpages to their browser.
- it can validate date.
- perform calculation in forms.
- validating form input.
- interact with multiple frames.
