Considerations for array literal notation in JavaScript

JavaScript can initialize arrays by array literal notation, however, ie and other browsers differ in handling the empty values of the array literal notation, as shown in the following code.

<script type= "Text/javascript" >var testarray = [1,2,3,];alert (' Length of Testarray is: ' +testarray.length);//IE: Length of Testarray is:4; Chrome:length of Testarray is 3;var str = ' All-in-all, '; var testArray2 = Str.split (', '); alert (' Length of testArray2 is: ' +testar Ray2.length);//ie:length of TestArray2 is:4; Chrome:length of TestArray2 is 4;</script>
