Assignment Help:

These are the central working units of JavaScript. Almost all the scripting code employs one or more functions to obtain the desired result. If you desire your page to provide certain a user-defined functionality, then functions are a suitable way of doing so. Thus it is significant that you understand what a function is & how it works.

 Function example (a,b)

{

number += a;

alert('You have chosen: ' + b);

}

The function made above may be called by using the following syntax.
