Filmed at 2019.dotjs.io on December 5-6, 2019 in Paris. More talks on dotconferences.com/talks
For a period of time, most of the mainstream frontend frameworks have converged on a class-or-semi-class-based model for declaring components. However, in the past year, we are seeing some new ideas emerging regarding how stateful logic inside components are declared, managed and composed.
Evan examines three different approaches: React Hooks, Vue Composition API, and Svelte 3. They share a common departure from the class-based models, but also have fundamental differences due to the trade-offs in their respective designs, which he discusses in this talk.

Honestly, I probably would prefer picture-in-picture more on these talks, bcs sometimes it's nice to see the code longer while speaker is talking

Yeah, I would imagine it affects the speaker in a bad way. Looks comfy for the audience, though.

The 2000 other audience are actually sitting, so just some have the chance to lurk. I think maybe the speaker feels more personal to this small audience, because he can focus on some people and doesn't see the big crowd (getting more nervous eventually)..

Couple of points related to the Svelte part -> * Svelte now supports TypeScript, so the plusOne example will work as normal in Svelte with TypeScript * You can reuse stores with Svelte simply declaring them in one common js file, solved !! ... no drama as mentioned in the Svelte stores part

Just a quick comment on your second point regarding Svelte Stores. I think you missed what he was saying. He did actually mention Svelte stores. He said that the stores API is different from the normal Svelte code you would write in your component. When he said you cant compose functions to share across components he was specifically talking in the context of "without switching to a different syntax like Svelte stores." Where as in Vue you can use the same syntax you use within components to share code across components. If you go to 20:11 where he shows the slide for that point, the slide even states "*cross component logic must use a separate store API" So, the criticism here isn't that its impossible to share code logic across Svelte. Its that you have to switch between multiple APIs to do it. Where as other solutions like Vue or React allows you to reuse logic easier by having a single API that allows for logic composability out of the box.
