Write a function in javascript to check if two strings are anagrams of each other. The function should be case insensitive. Example: LISTEN and SILENT are anagrams of each other

Example: check if anagram

function isAnagram(stringA, stringB) {
  // Sanitizing
  stringA = stringA.toLowerCase().replace(/[\W_]+/g, "");
  stringB = stringB.toLowerCase().replace(/[\W_]+/g, "");

  // sorting
  const stringASorted = stringA.split("").sort().join("");
  const stringBSorted = stringB.split("").sort().join("");

  return stringASorted === stringBSorted;
}
