Here's a project idea I'd really like to see: A version of Chromium, targeted at web developers, that is is modified to accept TypeScript syntax as a variant of JavaScript. This hypothetical browser wouldn't perform type-checking, just be able to parse TS syntax and convert it to plain JS, in the same way tools like Babel do. This would let you use TypeScript without the need for any transformation pipeline in dev. You could then separately run TypeScript in a console to get async checking. Then only when you build for production do you run everything through a compiler/bundler to get a plain JS bundle that will work in everyone's browsers.
