DESCRIPTION:

An anagram is the result of rearranging the letters of a word to produce a new word (see wikipedia).

Note: anagrams are case insensitive

Complete the function to return true if the two arguments given are anagrams of each other; return false otherwise.

 

Examples

• "foefet" is an anagram of "toffee"
• "Buckethead" is an anagram of "DeathCubeK"

 

코드

// write the function isAnagram
var isAnagram = function(test, original) {
  test = test.toUpperCase().split('').sort().join('');
  original = original.toUpperCase().split('').sort().join('');
  return test === original;
};
