Why window.Symbol looks like a constructor, but works like a factory? Wouldn't it make more sense to have either a regular constructor (let symbol = new Symbol()) or a regular factory (let symbol = createSymbol())? If it looks like a duck, it should also walk like one.

When subclassing, what is the advantage of [Symbol.toStringTag] getter over the toString() method override? Is it just another way to do the same thing?
