Returning a Value from a Function
== Returning a Value from a Function ==
In this example the function is called multiple times, passing through arguments that are then used in the function to construct a string to bne displayed in the alert dialog. To achieve this without functions it would ne necessary to repeat the script in the function 3 times over in the body. Clearly placing the script ina function and re-using it over and over is a much more efficient approach.

<body>
 
<h1>Calling a function</h1>
 
<script language="JavaScript" type="text/javascript">
sayHello( "24th", "July" );
sayHello ( "1st", "August" );
sayHello ( "24th", "May" );
</script>
 
</body>
