JavaScript: Tips of the Day
Checks if a string is an anagram of another string (case-insensitive, ignores spaces, punctuation and special characters)
Example:
const isAnagram = (str1, str2) => { const normalize = str => str .toLowerCase() .replace(/[^a-z0-9]/gi, '') .split('') .sort() .join(''); return normalize(str1) === normalize(str2); }; console.log(isAnagram('iceman', 'cinema')); // true
Output:
true
