You are given two strings, `word1` and `word2`.

Your task is to **determine if** `word2` is an **anagram** of `word1`. An anagram is formed by rearranging the letters of one word to produce another, using each letter exactly once.

You may assume that:
*   Both `word1` and `word2` will contain only lowercase English letters.
*   Neither `word1` nor `word2` will include any spaces.

Return `true` if `word2` is an anagram of `word1`, and `false` otherwise.
