What is JavaScript and what is it used for?
It is a script language used mainly to create scripts of browser behaviour. It can be used to animate a page (make it interactive), and solve problems that cannot be solved through html/css.
It is important that JavaScript is switched on on your computer, though it may not always be necessary.
