This is an excellent hindsight-2020 project, and the concept is overall an improvement on Node, but I'm afraid the ship has sailed and Node's momentum is too high to stop. Not that mainstream usage was ever its goal, it was basically a proof of concept for Ryan Dahl to demonstrate how he would do things differently if he could start over, and that yes, it would be demonstrably better than Node. On one hand I wish TypeScript got more love, but on the other hand its inherent unsoundness kind of makes me want something like ReasonML[1] to win out in the long term instead.

I actually like the structural system a lot, and found that combined typescript expressiveness, typing a code base with TS is much more intent driven and requires much less contortionism that a class-for-everything nominal system such as Java. In fact, we ported one of our java backend to node/TS, 40% less code, and as typed if not more. Also, there are simple ways to bring some of the nominal characteristics when needed, but in a language like JS where object literal is a intrasic part of the language, a structural typing system is great fit.
So, yes, their are different approach, but not sure soundness is a good description of those differences.
Now, if TypeScript is used to code JavaScript ”a la” Java, then yes, it could be seen as a loss of functionality.
