How can I get the last character in a string? [duplicate]

Question

If I have the following variable in javascript

 var myString = "Test3";

what is the fastest way to parse out the "3" from this string that works in all browsers (back to IE6)

Answer 1

Since in Javascript a string is a char array, you can access the last character by the length of the string.

var lastChar = myString[myString.length -1];
