re: Currently typescript gives me all the future features and rollup handles the bundling. It's working out better than I expected.

I'm talking about these features, like the pipeline operator.

Are they in TypeScript?

Class properties, decorators, default exports/re-exports, namespaces, numeric separators, and a few more are all there.

TypeScript has a few things that are actually not in that list like boilerplate constructors for declaring instance variables and null removal without if checking, e.g.

class A {
  constructor(readonly i?: SomeType) { }
const iValue = (new A(123)).i!;

If the pipeline makes it to the standard then it will show up in TypeScript but it is consistently ahead of the standard so I usually get all the nice features before they even end up in the standard.
