How can I compare two shuffled strings?

Question

I have the following two strings:

var str1 = \"hello\";
var str2 = \"ehlol\";

How can I check whether both strings contain the same characters?

Here's a modified version of Gurvinders answer.

var str1 = "hello",
    str2 = "ehlol";

// Add sort on prototype of String object
String.prototype.sort = function () {
    return this.split('').sort().join('');
};

// First check if length of both is same
var same = str1.length === str2.length && str1.sort() === str2.sort();
console.log('Strings are same?', same);
