human-asmjs VS proposals

One of my colleagues told me to stop doing that because in (I think) V8 these values are immediately converted back to a double nowadays. So annotating all code with |0 doesn't really add speed benefits there, just extra conversions between doubles and integers. Said colleague used to maintain human-asmjs so I trust he knows what he's talking about.

Memory64 is supported by a lot of runtimes now, although it isn't fully standardized yet (see https://github.com/WebAssembly/proposals), so no idea how reliable the implementations actually are, since I haven't had a need for that much memory yet

Block only. There’s a tail call proposal[1] that’s in phase 4 (nearly standardized).

While it'd be a nice addition, I wouldn't expect it any time soon.

It's currently still a stage 1 proposal, while we've been waiting for years for other proposals to be merged. The last time a proposal was actually finished was over 2 years ago.

Do you know anything about any WASM developments that will enable pure WASM interaction with browser's Web-APIs at no or at a low cost without the JS layer? I'm looking at https://github.com/WebAssembly/proposals and it's very confusing. There are type imports, almost complete GC proposal(which apparently only for GCd languages, but not for anything browser<->wasm), the component model(which looks and sounds as something not for the browser use case), JS String Builtins (which will provide faster JS strings, but not DOM) and ECMAScript module integration (which will turn WASM modules into ES modules, but Web-APIs aren't ES modules so no luck). Sometimes I read contributor interactions and it looks as if providing such functionality isn't their priority or even in their plans, and WASI + component model for cloud and similar use cases are more important.

It's already in Phase 4, so close: https://github.com/WebAssembly/proposals#phase-4---standardi...

Threads are Phase 3

And for Go, the proposal project on Github has many interesting conversations from the devs.

And as a reminder to anyone interested in using Go WASM, it’s experimental and does not come with the same compatibility promise as Go itself:

GC proposal is from 2018: https://github.com/WebAssembly/proposals/issues/16 and there’s code: https://github.com/WebAssembly/gc/blob/master/proposals/gc/O...

Seems like an awefully long time for progress to be made, given all the possibilities it would unlock.

The proposal was recently bumped to stage 4 (the penultimate stage) with at least a couple of runtimes working on implementing (besides v8, which has supported it for quite awhile now)

But basically it boils down to the memory control proposal, which can be found here and is not very far along; Webassembly proposals lists it in stage one.
