Anagram Checker

Function Name: isAnagram

Description

The function isAnagram should take two strings as parameters and determine if they are anagrams or not. An anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once. For example, 'listen' is an anagram of 'silent'. The comparison should be case insensitive and ignore all spaces.

Requirements

• The function must take exactly two string parameters.
• The solution must disregard cases and spaces, considering only the alphanumeric characters.
• The function should return a boolean value: true if the strings are anagrams, false otherwise.
• Empty strings or strings with no alphanumeric characters should be considered non-anagrams.
• The function should be efficient to handle long strings.

Examples
