Apart from const, which ones have TDZs?
All declarations whose initialization cannot be hoisted. My understanding is that that would be 'const', 'class' and 'private', although we have just dropped the latter from ES6. There might potentially be additional ones in future versions. But actually, what I perhaps should have said is that there is no other declaration that allows uninitialized access. That holds for all lexical declarations. /Andreas
