Ooh interesting. What is your machine and browser? On chrome with my m1 macbook it takes less than 1ms to compute and render each frame, but I am noticing some things I can optimize from the performance flame graph! I will say, I find chrom

I don't necessarily hate Lua, but I prefer C and Raylib for game dev. Lua is garbage collected, dynamically typed, strays far from standard syntax patterns, and has less existing tooling than C. I see why people might hate Lua. Especia

this is the way to go! making a move should automatically copy the new url to your clipboard. you can still keep the ascii charm by server side rendering the ascii chess board as an og description.

I'm guessing you don't consider VSCode an IDE? I'm curious, what features do you use in IDEs that are missing in VSCode?

These are great points! Thanks for the super thoughtful reply. I'm actually sold. 1. It's really nice that it's so easy to make a `createSignal` 2. I didn't realize that in Solid you had to update all the usage sites too

Whoops, I missed that. Good catch! I'm not sure how tln's problem is happening then.

Implicit reactive `let` statements make the code harder to understand for humans AND the compiler. This new explicit state pattern even simplifies designing. Now reactive state can work outside of components and across files as you would ex

Make sure you opt in to use runes! You can do it project wide or per component: https://svelte-5-preview.vercel.app/docs/runes

Instead of finding reactive dependencies at compile time, `$effect` and `$derived` automatically track dependencies at runtime. This might feel like it would result in a performance decrease, but it is what SolidJS has been doing. And Solid

Fair points, though React has hugely complex runtime magic. SolidJS's compiler magic is just as simple while also having much a simpler runtime.

To be fair, assignments to variables still update the state of your component. `count += 1` will still update the state of your component. I think what you meant is that you now need to explicitly declare `count` as state. Personally, I thi

> The $effect runes makes people think we are going down the React useEffect route... but I didn't see a dependency array attached there waiting to obliterate performance? This is exactly what SolidJS already does, and SolidJS is #1

If you created `anotherThing` as nested state, then just the children! See this for a real example: https://svelte-5-preview.vercel.app/docs/fine-grained-reacti... Here is the same thing in SolidJS with more explanatio

Most of this I really love. One thing seems a bit strange though... Let's compare Svelte's and Solid's approach to nested reactivity. Both of them implement the same nested reactivity todo example: Svelte: https://

by onsclom 3y ago
This example is a bit strange to me. I wonder if `$effect` will actually replace all usage of `onMount` and `onDestroy` for Svelte. In Solid you could totally do these things with `useEffect` too, but they chose to keep `onMount` and `onDes

I snooped around Rich's GitHub history and found he's working on esrap[1], a package to convert an AST into code. It uses Bun for development and testing! Crazy theory: esrap will be part of a transpiler that converts Svelte 4 cod

Whoops, I should have been more clear. When I said "It's all very unoptimized and dynamic QMLScript" I meant just the file `Flex.qml`. I'm sure the Qt C++ bindings are fast and great, but check out the `updatePositions`

It's really awesome someone did this. If you just want the expressiveness of flexbox and don't care about performance, this is perfect! However, wouldn't the performance for this be very optimal? Check out the `Flex.qml` code

> But in my view, the QML paradigm is extremely consistent, even migrating from Qt5 to Qt6 was quite straightforward. I just updated my website to a new NextJS version and so many things broke in React there were serious paradigm changes

I still don't get what advantage QML has over something like Svelte. Writing the QML backend with Rust would be nicer, but why wouldn't I just write my front end using Svelte/TypeScript with something like Tauri at that point
