It doesn’t and I say in my comment that it is not the same thing. Nevertheless it gives me the same uneasy feeling because you don’t know what features are going to creep into the language further down the road.
JSDoc is like 20 years old and not part of the javascript langage, it’s just a way of formatting some comments such that they’re programmatically process able.
It seems extremley unlikely that Javascript would ever make comments affect the runtime of the language. I'm not sure why there's a fear here why browser vendors/es standards comittees would opt to go down this road?
