Was WASM actually promised as a solution to performance problems in the browser? I always thought it was just meant to be a way to run code written in languages other than JS inside the browser. WASM itself doesn't have access to the DOM and still relies on JS bindings to modify the DOM, so wouldn't it be more performant to stay within the context of JS instead of needing to interop with another bytecode?
Regarding the latter part of your comment: I think Blazor (C#) basically ships WASM and interops with JS for the DOM API. They probably wouldn't do this if it was slower. I guess for very simple render processing calling a WASM module would be slower, but i bet that for many web apps out there written in React etc. it would be faster because the DOM isn't necessarily the slow part anymore. React popularized using a VDOM which is a massive reduction in DOM calls compared to what tools did before. And regardless of if you accelerate using a VDOM or VDOM-less like Solid.js or Svelte, i'm confident that they MIGHT be faster with WASM - it's just a MASSIVE amount of work and MUCH worse DX.
Yes, I suppose this was the reason for it, to use libs and code not written in JS, in the browser. Though, just as you have webAPIs querying and exposing browser capabilities, you could have something similar for hardware, some kind of WASM API querying and exposing OS capabilities. And yeah, native code meant for this or that specific hardware is always gonna be faster than any JS interpreting engine. WASM will win over JS, since not only there won't be any specific reason to pick JS, your capabilities on what you can and cannot do are gonna increase to near native level programs, and as a bonus, it's gonna run faster regardless of your lang of choice.

I constantly checking the state of wasm every year and i wrote some complex wasm apps in the past.

It looks like it will not change until native GC support will be included 2) wasm and all compilers / frameworks etc. are lacking in developer tools or lets say not lacking: it could be better. That for, i think if the tech. chain is smaller less cross compilation etc. it helps a lot. 3) also the glue code is important, i mean compiling to wasm is one thing but writing glue code by yourself or not getting a viable one is a pain in the a***. Just my opinion and experience.
A good example of when I'd use WASM today is with the Rapier physics engine. There's also a wrapper for react-three/fiber which integrates it really well.
People are missing the main goal of this tool. It is basically a JS Engine without the JS embedded interpreter. It has a potential to improve JS binaries size down if you compare with Bun or Deno as it won't pack a JS interpreter inside it. V8 is already fast but it needs to do a bunch of memcopy to pass stuff around navite and JS code, so this Porffor has the potential to reduce the memory footprint of JS server applications. The main purpose is not to run it in the browser context as people pointed out, wasm won't have access to the DOM so you're better off using JS directly there.
I love how you pronounce Hermes like the fashion brand Hermès 😂 It's actually named after the greek patron god of merchants, thieves, and travelers. They even named the Garbage Collector "Hades", the greek god of the underworld/dead as it cleans up all the "dead" memory... lol
One thing that's interested me about Porfor is, you get to control the execution in a way that you can't really in current JS runtimes, in a web app you can eval() and that code can run for as long as it wants. Sure you can put code in a Worker and stop it then, but you can't, say, intercept a call to alert() and have it behave the same way as it would if it went directly to the browser (i.e. you can't synchronously wait for something to happen in JS)
What I expected, when WASM come out, WASM can perform DOM operation as Javascript. Convert all the bulky JS into small and beautiful WASM binary. Until now, WASM is nothing changed. Very Disappointed.
If you're hoping for small WASM binaries, you're always going to be disappointed. In my experience, most WASM binaries are bigger than the equivelent js code, which you would expect for a low level vs high level language.
AssemblyScript doesn't allow plain js, and relies on types for compilation. It also has its own standard library, compared to porffor which implements javascript's
Try to pass array to assembly script and get it modified back. It will be slower than vanilla js... Time loss happen when it passes array between js and wasm.
WASM is really cool tech and I get so excited every time I see any developments in the WASM world because it has so much potential. That said, if you can run any language in the browser why JavaScript , like I get you still need JS for DOM manipulation but if you cause anything but JavaScript - why don't you. This feels like it take a problem WASM has and makes it worse
I think Javascript is still a really cool transpiler target. Most languages already have one, and then you can go from there to WASM. Especially once the garbage collector is considered stable, it's better to implement it once, instead of thousands of times.
4:13 doesn't v8 automatically detect hot code (the isPrime function) and compile it further to "machine code"? i'm pretty sure that's the case, and if so, microbenchmarks like this probably don't showcase the power of porffor/js-to-wasm as much as most normal code bases would benefit
Blazor now supports server side components rendered with wasm. The memory management is probably a workload on the server being expensive but consumers will have a smooth experience that also supports typescript. Techempower has C# as one of the fastest languages to make API’s
server side components + WASM? what do you need WASM for when the server does the rendering? i thought blazor uses WASM for CSR - that's the only usage that makes sense to me.
Blazor actually works pretty nice in WASM. About the only bad thing about its implementation, is that the code is, well, trivial to decompile as dlls are sent to the browser - but there wasn't really a way around that. So you have to be extra careful of not storing secrets nor proprietary code there. That in combination with Blazor united / hybrid works beautifully for those scenarios where you want to server some static content while the rest of the application is being downloaded.
I kinda hate the entre JS runtime thing. First we ended up with thousands of frameworks, each incompatible with the others. Now we're effectively ending up with 5+ different JS flavours, simply because these new runtimes are popping up like mushrooms after a rainy day. One runtime would handle buffers its own way, another would handle connections and sockets differently, yet another will handle cryptography and compression differently and omg why did I go for JS and not something else...
this is...just an uninformed take. No matter what, things like image manipulation, audio processing, games, low-level management of primitives like strings, etc. will always be slower and use more memory in JS. Memory usage is a big one, as JS' garbage collection implementation means you can only optimize it so far.
@@PraiseYeezus OP really needed to add ".. when used for the intended purpose" to their statement, agreed. Blazingly fast might be a stretch, but it is pretty decent & the skill issue aspect is valid.
WASM just physically can't be faster than JS compiler by V8, the only way to make it faster is to change how js works, perhaps by introducing real data structure and preventing you to append whatever to any object, only a subset of js can be faster than js.
Hold on .... when the javascript runtime is causing node.js to consume so much memory, why doesn't node.js have a mode that unloads all the interpreting and compiling stuff after it is done interpreting my javascript?
You're running JS locally while running the WASM either on their servers or the browser. You should measure time under the same environment and same conditions.
@@theairaccumulator7144 but inside chrome it's running under chrome, outside of chrome it's running native no? Anyways, I would still do it to be super safe before I make any conclusions haha.
At first I was like "HA, another way to use WASM for CRUD apps! LAWL! Way to bring an uzi to a knife fight!" ... But really those memory usage and binary size gains are nothing to sneeze at. 🤔
Shouldn't ts -> wasm be faster than js -> wasm because of how you optimize with static types? Sounds like a natural progression with ts -> wasm throwing out the intermediate js. I get that's not what or why porffor, but as a general idea?
We've had quick.js for this for ages, how is this different? Pure JS implementation vs a C implementation, but I'm not sure that works in its favor? Also has "WIP" and "unstable" all over the porffor readme, doesn't seem anywhere close to being ready for prime time.
quick.js is an interpreter, so if you use it to run javascript as wasm, you have to bundle the whole quick.js runtime porffor does that ahead of time, so it doesn’t need all the bloat of a whole interpreter
If done right, this could have far better perf in cases where you have lots of "cold" code, where JIT would take a while to kick in. A simple for loop would not be much faster.
The beginning example doesn't seem optimized to me, in terms of the WASM generated. The compiler accepts optimization switches. Though adding -O3 didn't help much. It does seem like it's running on their servers as the performance I'm getting is near identical to your's. But still for whatever reason number is an f64, while in fact it will never be a float. So it should be an i32 or i64. As it doesn't seem to work on typescript, it must be up to the compiler to determine what should be which type. Number has no business being a float.
All numbers in javascript are doubles (not including bigint). that is a possible opportunity for optimization though (determining what numbers never have decimals and optimizing into an integer type). v8 does that
The advantage of WASM is not in such simple programs - it's in advanced compile time optimizations. Ask C devs how different gcc is performance wise compared to the '90s. Yes, we have AoT, but it is always a trade off - if we can do all the static analysis at compile time then it is a pure gain.
I do not ever see this working as a wide scale "just compile all JS to WASM" solution. The reason is that JS is full of all those WAT-style weidnesses around its operators and the variety of parameters they can take. You just don't know how much JS code may depend on some non-obvious behavior of the language. The code Perffor is producing (isPrime for example) is very numeric centric. Pass in a string or a null and that code will not behave the same as it did in JS. So, to truly make a function behave the same, you have to pepper your WASM with all the conditionals to emulate all that stuff, which would slow it back down to JS levels or probably even slower.
I have multiple videos about why it's good to be "behind" the curve. I'm relatively late to actually adopting new stuff, I just get excited and like sharing that excitement :)
Is wasm a way to avoid someone stealing your code? Javascript nowadays is a serious programming language, the only thing that stop me to going pro is bc someone can steal all your files, so im thinking to go full kotlin multiplatfom.. in 3 months
WASM, with all its hype and interest, is moving really slow.It's far from a practical target for a lot of languages and frameworks yet. I don't think we necessarily need to support higher level features that are in JS, and it's understandable that it will always be a poor choice for dynamic languages but at least support calling the browser APIs, garbage collection, and finish the work on Interface Types. Until then, I don't see people deploying any web apps in WASM.
I think it's unfortunate that WASM got stuck with the component-model and interface-type proposals that would have allowed WASM to be a true JS replacement. The current state where you have to access the DOM via JS is a bit unfortunate, but performance-wise there are libraries like leptos that come very close to native JS. The most promising use case for WASM today is using WASM as a secure (and more portable) alternative to containers. Especially for edge use cases, WASM can scale much faster while being much more secure compared to bulky container images. The Kubernetes community is pushing WASM very hard for this, and with projects like WASI solving the I/O situation, it could be a good replacement for 80% of all containers.
WasmGC is what you are looking for as a JS replacement. It offers strongly statically typed garbage collected high level types that it interacts with and passes around, even into JS and back. Now is the perfect time for a language to take advantage of this and truly seemlessly integrate it into the JS ecosystem. In fact there is a TypeScript to WasmGC compiler which technically competes with Porfor, that isn‘t mentioned in the video.
WASM wasn't designed to address performance issues. It wasn't designed to enable other languages. It was designed as obfuscation and copy/paste barrier of corporate code, everything else is a coincidental feature, or rather clever phrasing to hide the intent.
@@cormickholland3855 "Design" the noun vs "to design" as verb. Think of it this way, there are design goals that are set at the start of project and might shift during a project. Then there's the process of implementing a design, which can influences the outcome and might not match the initial goals. Matching standing design goals exactly is sometimes extremely hard, or during implementation of a design goals turn out to be nonsensical. So the implementation of a design is as much part of design as the definitions of the design goals. So if you look at the current state of the implementation of the design, you notice the most often mention and criticized lack of DOM interoperability, but also the somewhat cumbersome JS interface. So I'm not implying malicious intent, just by judging the current state of WASM, it really serves the case of obfuscation a lot better than the case of JS equivalent runtime. Now go and check the WASM community chairs, and notice their affiliations. Now think about how consensus among such committees generally works and the power chairs hold over the consensus process just by personality alone. And because all people hold biases now you can see how certain biases in design goals and implementation could happen even completely without malicious intent.
Most webdev use js, but what's the issue? If another language is better, they will need to adapt and learn a new language, not a big deal If they only can use js because they only did a 6 months bootcamp, that's a different story
Personally, I think wasm is a huge disappointment. I'd rather see Java make a resurgence as a browser language over ever using wasm. Although, we should have a runtime like Java built into the browser and having multiple languages should be no problem. We just need a VM that is more open for usage and not actually the JVM. In fact, if the web browser was just a glorified renderer for some VM-based language, we'd be far better off.
The fact that you are benchmarking the log rather than the actual prime logic is triggering 🫠 (this is the whole point of using this custom porffor func instead of log)

Is wasm a way to avoid someone stealing your code?
Javascript nowadays is a serious programming language, the only thing that stop me to going pro is bc someone can steal all your files, so im thinking to go full kotlin multiplatfom.. in 3 months
For most of the video, I thought a group of ex Firefox devs were working on this
Reminds me of compiling Python into C code...

WASM, with all its hype and interest, is moving really slow.It's far from a practical target for a lot of languages and frameworks yet. I don't think we necessarily need to support higher level features that are in JS, and it's understandable that it will always be a poor choice for dynamic languages but at least support calling the browser APIs, garbage collection, and finish the work on Interface Types. Until then, I don't see people deploying any web apps in WASM.
I think it's unfortunate that WASM got stuck with the component-model and interface-type proposals that would have allowed WASM to be a true JS replacement. The current state where you have to access the DOM via JS is a bit unfortunate, but performance-wise there are libraries like leptos that come very close to native JS. The most promising use case for WASM today is using WASM as a secure (and more portable) alternative to containers. Especially for edge use cases, WASM can scale much faster while being much more secure compared to bulky container images. The Kubernetes community is pushing WASM very hard for this, and with projects like WASI solving the I/O situation, it could be a good replacement for 80% of all containers.
WasmGC is what you are looking for as a JS replacement. It offers strongly statically typed garbage collected high level types that it interacts with and passes around, even into JS and back. Now is the perfect time for a language to take advantage of this and truly seemlessly integrate it into the JS ecosystem.
In fact there is a TypeScript to WasmGC compiler which technically competes with Porfor, that isn‘t mentioned in the video.
Good luck debugging it on your next bug ticket.
WASM wasn't designed to address performance issues. It wasn't designed to enable other languages. It was designed as obfuscation and copy/paste barrier of corporate code, everything else is a coincidental feature, or rather clever phrasing to hide the intent.
what makes you think there’s malicious intent behind it? you shouldn’t throw out accusations like that without anything backing it up
@@cormickholland3855 "Design" the noun vs "to design" as verb. Think of it this way, there are design goals that are set at the start of project and might shift during a project. Then there's the process of implementing a design, which can influences the outcome and might not match the initial goals. Matching standing design goals exactly is sometimes extremely hard, or during implementation of a design goals turn out to be nonsensical. So the implementation of a design is as much part of design as the definitions of the design goals. So if you look at the current state of the implementation of the design, you notice the most often mention and criticized lack of DOM interoperability, but also the somewhat cumbersome JS interface. So I'm not implying malicious intent, just by judging the current state of WASM, it really serves the case of obfuscation a lot better than the case of JS equivalent runtime. Now go and check the WASM community chairs, and notice their affiliations. Now think about how consensus among such committees generally works and the power chairs hold over the consensus process just by personality alone. And because all people hold biases now you can see how certain biases in design goals and implementation could happen even completely without malicious intent.

That's just running CPython in the browser, not compiling python to wasm
Soo Gleam gets another target for free? ^^
Compile your js to asm and use exploits to run it in the client browser or even kernel.
wasm isnt asm
@@mrkostya008 I meant what I said.
It seems that to you anything more complicated than JS is pure magic that can do anything, just because you don't understand it.
@@mrkostya008the joke went over your head. ASM is correct…
CanadaHonk loves to abandon projects a lot, so that might die after what 3 weeks?
or we could just stop using js for the server :)
fuck this shit. i'm gonna make a BIG and SLOW JS Compiler.

some JS mods use it and it's dumb, imo.
At the end of the day you are down to a TH-cam bot
Most webdev use js, but what's the issue? If another language is better, they will need to adapt and learn a new language, not a big deal
If they only can use js because they only did a 6 months bootcamp, that's a different story
The point is to make browsers language independent, so you can use whatever language you want, because in the end it will still be compiled to WASM.
Personally, I think wasm is a huge disappointment. I'd rather see Java make a resurgence as a browser language over ever using wasm. Although, we should have a runtime like Java built into the browser and having multiple languages should be no problem. We just need a VM that is more open for usage and not actually the JVM. In fact, if the web browser was just a glorified renderer for some VM-based language, we'd be far better off.
tbh wasix is way more interesting than browser wasm
sadly the wasix developers tried to trademark "WebAssembly", so nobody likes them anymore 👎

The fact that you are benchmarking the log rather than the actual prime logic is triggering 🫠 (this is the whole point of using this custom porffor func instead of log)
