> If Node.js can run TypeScript files directly, then the TypeScript compiler won't need to strip types and convert to JavaScript Node.JS isn't the only JS runtime. You'll still have to compile TS to JS for browsers until all the browsers can run TS directly. Although some bundlers already do that by using a non-official compiler, like SWC (the one Node's trying out for this feature). > In Python, I've even heard of people writing types in source code but never checking them, essentially using type hints as a more convenient syntax for comments. It's not just comments. It's also, like the name "type hint" suggests, a hint for your IDE to display better autocomplete options.
