Is Anagram

Giovanny Gongora

Checks if a string is an anagram of another string (case-insensitive, ignores spaces, punctuation, and special characters).

const isAnagram = (str1: string, str2: string) => {
  const normalize = (str: string) =>
    str
      .toLowerCase()
      .replace(/[^a-z0-9]/gi, '')
      .split('')
      .sort()
      .join('');
  return normalize(str1) === normalize(str2);
};
