Spot the bug - #68

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.

lol this is a classic “one pixel off” bug — toLowercase() doesn’t exist on strings.

JS wants toLowerCase() (capital C), otherwise you’ll hit a TypeError: ... is not a function at runtime.
