JavaScript code question

[Arjun Reddy]

Hi All,

I am unable to understand myArray[4] and line no 8 from the below code. Can someone explain me what it means?

<script type="text/javascript">
var myArray = [ 3, 'hello!', function() {return 5}, {'color':'blue', 'budget':25}, /[ell]/i ];
document.writeln('0>'+myArray[0]+'<BR>');                  // Will output: 0>3
document.writeln('1>'+myArray[1]+'<BR>');                  // Will output: 1>hello!
document.writeln('2>'+myArray[2]()+'<BR>');                // Will output: 2>5
document.writeln('3>'+myArray[3].color+'<BR>');            // Will output: 3>blue
document.writeln('3>'+myArray[3].budget+'<BR>');           // Will output: 3>25
document.writeln('4>'+myArray[4].test(myArray[1])+'<BR>'); // Will output: 4>true
</script>

Thanks.

I hope this is just academic code and not something that's actually being used for anything!

In any case, [4] is a regular expression, which possesses a test() method which is being called.

I found it on this page actually.

Please do not consider it any sort of valid programming style!

Eeeesh!
