Answer 1

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).

Answer 2

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.
