TypeScript

I think it'd be interesting just from the standpoint of we've seen them adopt other stuff right. They're like promises came out in the library and then they adopted as part of the language. But they didn't adopt kind of the tried and true way that the library worked in every case. And so I'm curious to see how similar it is to TypeScript and whether or not it would bring those aspects into JavaScript or not. It's always a question of when they were, if they were to stick on one way that's different from TypeScript,. Then what happens next in terms does TypeScript adopt that?
