JavaScript anagram comparison

Question

I\'m trying to compare two strings to see if they are anagrams.

My problem is that I\'m only comparing the first letter in each string. For example, \"Mary\" and \"

Answer 1

This considers case sensitivity and removes white spaces AND ignore all non-alphanumeric characters

function compare(a,b) {
    var c = a.replace(/\W+/g, '').toLowerCase().split("").sort().join("");
    var d = b.replace(/\W+/g, '').toLowerCase().split("").sort().join("");
        return (c ===d) ? "Anagram":"Not anagram";
}
