javascript function that specifies whether two words are anagrams

anagram.js

// Anagrams are two words with exactly the same letters. Order does not matter. Define a method that, given two strings, returns a boolean indicating whether they are anagrams.

function anagram(str1,str2){
    if (str1.length != str2.length){ //if the words aren't the same length, they aren't anagrams
        return false;
    }else{
        if(str1.split("").sort().join("") === str2.split("").sort().join("")){ //String comparison, clever? if the sorted characters of the words aren't the same, they aren't anagrams.
            return true;
        }else{
            return false;
        }
    }
    
}
