Another simple one for the collection 
What's a variable? I hear you say....
Answer: A variable is a place in which you can store data
When you come to naming variables you must be aware of certain things. A variable can have any letter, digit and even the underscore "_" may be used, but the variable may not begin with a digit.
Example of valid variables:
abcd
my_variable
var32123
To create a new variable, you use the Javascript "var" keyword.
I'll show you with a small script.
<script type="text/javascript">
<!--
var my_message = "My First JavaScript Variable";
alert(my_message);
//-->
</script>
The text string is stored inside the variable called my_message.
Then the variable name is called to the javascript alert function, so when you run the script you will get an alert box displaying the string which is stored in the variable.
