you can also count the letters in a fixed length array. for e.g:
` let d = "hello"; let k = "holle"; const arr = new Array(26).fill(0); const arr2 = new Array(26).fill(0);
for(let i = 0; i < d.length; i++) { arr[d[i].charCodeAt(0) - 'a'.charCodeAt(0)] += 1; arr2[k[i].charCodeAt(0) - 'a'.charCodeAt(0)] += 1; }
return arr.join(",") === arr2.join(",") `
