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?

You could possibly say this:

(a.length === b.length) &&   (a.split('').every(function(val) { return b.indexOf(val) > -1}))

And, in ES6 you could make it look as follows:

(a.length === b.length) && a.split('').every(val => { return b.indexOf(val) > -1 })
