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 bug — JavaScript’s string method is toLowerCase() (capital C), so this throws “toLowercase is not a function”.

Change it to tag.trim().toLowerCase() and it’ll log javascript.
