Compile to webassembly

ScratchBrother123

Is it possibile to compile scratch projects to webassembly, or is anyone interested about it?

It looks like using this you can convert JavaScript to web assembly, and you can convert scratch to JavaScript using turbo warp packager or leapord.Ja so it should work?

Im working on a thing that does this it might be ready soon (but probably not)

What benefits would you get out of compiling Scratch code to WebAssembly? Scratch uses WebGL 1.0 for the GUI, so you won't get much rendering performance by using WASM

Good evening. I am a gerbil. Are you a gerbil? I know I am. Gerbils are possibly the most important beings in the universe; they are super intelligent and they eat carrots so we don't have to.
If you are reading this, you're probably thinking one of 3 things:

This dude's not a gerbil, he's a pufferfish/human/bison/whatever other organism/inanimate object you mistakenly believe I am.
Why am I reading this????????
I'm hungry

The first one is INCORRECT, and I'm going to have to ask you not to spread that false rumour.
The second one is a valid question, and one that has no satisfactory answer other than that you're really ,really, really bored.
As for the 3rd one - so am I. You're not alone.

It isn't an interpreter written in WASM, it converts Scratch code to native C++ code, which speeds up the actual code.

there are now 5 things that compile scratch to C++/rust now

mine doesn't compile to rust but ok

things that I hope to get out pf using WASM:

if the types of variables can be statically determined then most operations should be a bit faster than in js
if not but you can make a pretty good guess then you could utilise branch hinting (currently available in safari & chrome behind a flag) which would hopefully improve things
if you've got clones doing the same thing as each other each tick SIMD may be usable (although probably not)
most importantly, wasm's performance is fairly predictable across browsers, unlike js which tends to be slower in ff - so the largest performance increass would probably be seen in ff

of course js JIT engines are really good these days so there's a chance that there won't be any improvement at all

also i'd assume that graphics wouldn't gain any performance boost from using wasm, webgl will almost certainly be faster - however of course there is overhead from wasm<–>js interop so using wasm could just make everything slower… but then again copying data to and from the gpu is already expensive
