Structs in JS might change everything 

eventually JS becomes Rust because on a long enough timeframe everything evolves into a crab.

never thought I'd live long enough to see the unsafe keyword in js 🎉

As someone who switched from TypeScript to Rust and Go I find this hilarious but also super cool. This is why JavaScript is the GOAT of programming languages. It is like an endlessly evolving Pokemon. 🤣

This is going to help WebGPU and React Three Fiber immensely.

Finally something good in JS-land. I hope we don't have to wait 10 years for this proposal to be implemented. Temporal, where you at?

I have no idea what any of this is coming into it but damn is it interesting and helpful in understanding what code is capable of.

This will give a pretty nice boost to most JS projects and unlock the potential of using JS for more compute heavy workloads for which other languages are preffered atm (e.g. Python).

I know it a short sponsorship but can you do another video explaining what that service is actually is. Have seen a lot of ads and i still don't know what it is ?

So actual classes are coming. Cool, cool.

Good initiative overall, will help certain libs to become faster. I don't see the Rust analogies some are talking about though, unless it's just for jokes. Because a) there's nothing analogous to Rust's compile-time memory safety features like the borrow checker. And b) this still feels quite primitive compared to what you can do inside unsafe blocks in most application-level languages, never mind Rust, which is usually near-full access to process memory via pointers... if you're feeling risky.

as a webworker aficionado and someone who does a lot of ffi in deno, this is super exciting

as a person that has been using JS for the past 10 years in different projects(mainly frontend no serverside) I'm starting to not know JS any more but the struct thing, making a un-chagable class could have been fixed with a one time use parameter in it that if it's true then you can't change it from outside (basiacally what other languages did with allow dynamic attributes default off). The struct now makes me want to use typescript even less since it was the main thing that people advocate for

Tearing: As you're writing your name on a piece of paper, your annoying classmate is add af and rips it from your hands

This is actually really cool.

Everything will be written in javascript

React to the latest Deno 2.0 ad!

16:58 it they didn't implement that (tear free property read write) web pages could cause native access violations or access memory that should not be accessible

I want this to be an easy way to share objects with wasm instances

When are you uploading the thing you did with Dan

The audio not working comment makes me feel seen, and hurt at the same time 🤣

What is assertThrows()? Is that some library, or new JS syntax?

Everything is having a rough time of it lately, it's getting changed all the time apparently lol

Just make Go compile to JS. That should be the web assembly LOL

Meh, to me javascript is about fast development not having to think too much about performance or memory 99% time, and that is a good thing. This trend of having javascript do everything, absorbing foreign syntax from other languages is kind of sad. Limitations are good.

This will just make a lot of bad code possible, whilst still requiring a ton of runtime checks. It will not believe, that the performance will be drastically better, without hard data. Doing anything this high performance should be a wasm only optimisation imho. These optimisations would be need to be done in the JIT in the Runtime, since there is no build step for JS. We then will see tradeoffs between Running stuff in a single thread vs. incuring startup cost with the optimisation steps. If you want optimal assembly, then ship optimal to the browser, dont just hope the browser will build that for you. Think of it as SSR for high-performance code.

struct.... but fields are undefined at the start... oh no. methods wut? inheritance?! hold on... unsafe? They should leave off methods, and add traits instead.

Waiting for them to touch Lifetimes since they want to be Rust hahahahahahhaah

its golang

Just change the syntax to Go

yoo js will become a real language we'll do FFI without hassle! want a database? sure champ, just memcpy this into that file lmao and if this gets into the browser we'll have zero copy WASM

always love your videos sir! I always watch them to myself up to date on the latest tech news. Cheers man!

So i will be forced to learn rust by coding in JS... well interesting :/

well now js is unsafe++

Unsafe? Every js code is already unsafe 😂

'That's comming from somebody whose audio doen't work right now' 🤣🤣🤣. Just move from Linux to Windows again becouse all this annoying problems.
