IE9 javascript undefined errors

Question

I tried fixing my application to work on IE9 browser (with IE9 standards mode).

However I am getting some undefined javascript errors..

I have the following piece of code in a js file.

1.

if(escape(String.fromCharCode(111)).toLowerCase() != "abc")

{

    //code

}

I get error 'escape' is undefined.

2. In some js files, I get errors "Array is undefined" for such piece of code

//1
function abc(){

this.abc = new Array();

}


//2

var cde = new Array
(

  "aaa","bb","cc",

  "dd","eee","ff",  

);

However these errors do not occur for IE8 standards mode and other modes.

Please let me know why these errors are coming and how to fix such errors.

Answer 1

While Ryan's answer fixes the issue, the problem here is the trailing comma;

"dd","eee","ff",
