JavaScript Variable
You create a variable with or without the var 
statement
var strname = some value
strname = some value
When you declare a variable within a function, the 
variable can only be accessed within that function
If you declare a variable outside a function, all the 
functions on your page can access it
The lifetime of these variables starts when they are 
declared, and ends when the page is closed

JavaScript Funcitons
A JavaScript function contains some code that will 
be executed only by an event or by a call to that 
function
>
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> 
section
>
As a convention, they are typically defined in the <head> 
section
17
Example: JavaScript Function
<html>
<head>
<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!")
}
</script>
</head>
<body>
<form>
<input type="button" value="Click me!"
onclick="displaymessage()" >
</form>
</body>
