Anagram Detection.js

// 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"

// write the function isAnagram
var isAnagram = function (test, original) {
  test = test.toLowerCase().split('')
  original = original.toLowerCase().split('')

  while (original.length > 0) {
    const f = original.indexOf(test[0])
    if (f === -1) return false
    test.splice(0, 1)
    original.splice(f, 1)
  }
  return true
}
