Functions

Calling a Function in new Function

In JavaScript, a user can call a Function from another Function such as:

<script type=”text/javascript”>

function firstCandy()

{

document.write (“ Hersheys”);

}

function secondCandy()

{

document.write (“ Toblerone”);

}

function goodCandy(){

firstCandy();

secondCandy();

}

goodCandy();

</script>

Output:

Hersheys Toblerone

Calling a Function within Function:

When we try calling the Functions within each other, it prints results like never ending cycle. It is bad programming.

<script type=”text/javascript”>

function firstCandy()

{

document.write (“ Hersheys”);

secondCandy();

}

function secondCandy()

{

document.write (“ Toblerone”);

firstCandy();

}

firstCandy();

</script>

Output:

Hersheys Toblerone Hersheys Toblerone Hersheys Toblerone Hersheys Toblerone

Hersheys Toblerone...
