javascript algorithm for detecting anagram in a sentence code example

Example 1: javascript anagram check

const areAnagram = (str1, str2) => str1.toLowerCase().split('').sort().join('') === str2.toLowerCase().split('').sort().join('');

// Examples
areAnagram('listen', 'silent');         // true
areAnagram('they see', 'the eyes');     // true
areAnagram('node', 'deno');             // true

Example 2: anagram js

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;
}
