Why is !true ? 'false' : 'true' returning 'true'?

Question

Why is it that when I do

(!true) ? 'false' : 'true'

it returns 'true'?

Answer 1

It simply means

if (!true) {
  return 'false';
} else {
  return 'true';
}

!true (not true) means false, so the else is returned.

Answer 2

Because (!true) is false, and then the right side of the : is chosen.
