Check Anagram

Problem

Create a function that checks if two given strings are anagrams of each other.

An anagram is a rearrangement of the letters of one word to form another word, using all original letters exactly once.

Return true if the second string is an anagram of the first string; otherwise, return false.

Examples

isAnagram("listen", "silent")
// true

isAnagram("hello", "bello")
// false

isAnagram("act", "cat")
// true
