JavaScript Funcitons
A JavaScript function contains some code that will 
be executed only by an event or by a call to that 
To keep the browser from executing a script as soon as the 
page is loaded, you can write your script as a function
You may call a function from anywhere within the 
page (or even from other pages if the function is 
embedded in an external .js file).
Functions can be defined either <head> or <body> 
As a convention, they are typically defined in the <head> 
Example: JavaScript Function
<script type="text/javascript">
// If alert("Hello world!!") below had not been written within a
// function, it would have been executed as soon as the page gets loaded. 
function displaymessage() {
alert("Hello World!")
<input type="button" value="Click me!"
onclick="displaymessage()" >
