This text cleanup has one bug.

function normalizeTag(tag) {
  return tag.trim().toLowercase();
}

console.log(normalizeTag('  JavaScript  '));

Reply with what is broken and how you would fix it.

toLowercase() is the broken bit — JavaScript’s string method is toLowerCase() with a capital C, so your function will throw TypeError: tag. trim(. . . ). toLowercase is not a function. Fix:

function normalizeTag(tag) {
  return tag.trim().toLowerCase();
}
