Typescript isn't a standard though, it's one company's implementation of type-checking for JS. Hopefully, the lessons learned from Typescript, Flow, Dart, etc. will be fed back into the TC39 committee and be used to inform an actual standard for optional types in a future version of EcmaScript.

At that point, is think typescript should basically become the official next version of javascript (with the added modification to have things like import work in a browser).

That would save everybody time. Imagine google, facebook and microsoft agreeing on that, and i think it wouldn't take more than 6 months to see it working in chrome, internet explorer and all the other major browsers would follow.

With the new microsoft, and now facebook and google talking to each others, this is the first time something like this could actually become a reality.
