proposal-dynamic-import

ES Modules have dynamic imports (https://github.com/tc39/proposal-dynamic-import). The proposal is at stage 4 and is available from Typescript 2.4. We're on version 4 now so I'd expect Deno to have it. I'm not sure what you mean by "bad practices like include files" so I can't comment on that. I've found most Javascript developers prefer the await syntax with promises to using callbacks. It gives the code the appearance of being synchronous with the ability to do things more asynchronously if you need. I haven't encountered many who actively prefer the callback style. It gets unruly fairly quickly. I can't see optional type annotations ever being added to Javascript. They would have to be checked at runtime which isn't something I'd imagine browser vendors wanting to implement. The feeling that I get is that the standards committee is try

A minor nitpick, but the dynamic import proposal [0] is actually in stage 3 of the TC39 process [1]. Although you are correct that the WHATWG HTML spec requires implementing the import() proposal if JavaScript is supported.

The `import<TModule>(url: string): Promise<TModule>` syntax/special function was what the TC39 committee agreed to for lazy/dynamic imports after much bikeshedding. It's a Stage 3 ES proposal [1], which means it is likely in the next ES spec version, and is already supported in some browsers and many tools (such as webpack).

> You actually can reflect on module exports and dynamically change them with node modules; you can't do it with ES modules, but that has the significant advantage of enabling static analysis. And yet even that advantage got thrown out from the language with the introduction of "import()". Apparently static analysis is a non-goal (see discussion in [1]).

I would argue that the future of JS looks bleak when you effectively can't have any meaningful discussions about proposals if you are not in the committee (the author just ignored the issue for half a year, then closed and locked it): https://github.com/tc39/proposal-dynamic-import/issues/35

From what I have been told, this proposal is likely to win out: https://github.com/tc39/proposal-dynamic-import

Checkout the import() proposal: https://github.com/tc39/proposal-dynamic-import It basicly is what you are describing.
