You can use React in TypeScript with the type definitions here:
https://github.com/DefinitelyTyped/DefinitelyTyped/tree/master/react
My team is using React in TSX which references AS libraries typed with
as2dts. For my work, the major advantage AS has over TS is the is/as
operators which can check if something implements a particular interface at
runtime. Interfaces in TypeScript cannot be referenced at runtime.
You could conceivably build something that directly converts ActionScript
with inline XML into TSX or JSX, but I don't see the value in that since
ActionScript does not have as many strong typing features as TypeScript
has. A slightly different approach would be to map the MXML life-cycle
onto the React life-cycle so you could build your GUI in MXML rather than
TSX or JSX. The difference would be if you already know MXML you would not
have to learn or care about the React life-cycle. I haven't thought of how
much work that would be.
