An anagram is a word or phrase formed by rearranging the letters of another word or phrase. To check if two words or phrases are anagrams in JavaScript, you can follow these steps:

  1. Convert both words/phrases to lowercase to ensure that case sensitivity does not affect the comparison.
  2. Convert both words/phrases to arrays of characters.
  3. Sort the arrays of characters.
  4. Compare the sorted arrays of characters. If they are identical, then the words/phrases are anagrams.

Here is some sample code that demonstrates these steps:

function isAnagram(word1, word2) {
  word1 = word1.toLowerCase();
  word2 = word2.toLowerCase();
  var word1Chars = word1.split('').sort();
  var word2Chars = word2.split('').sort();
  return (word1Chars.join('') === word2Chars.join(''));
console.log(isAnagram("word1", "drow1"));

This will output ‘true’ if the two words passed as arguments are anagrams.
