Would be interesting if they compared also other WASM frameworks.

Obligatory: sad state of web where React is so popular.

I wonder why the article used old versions of React and Svelte? It is using React 17 and Svelte 3.

It's worth pointing out this article is discussing Svelte 3.x when the current version is Svelte 5.x and has some significant departures from previous versions (i.e. the introduction of runes)

I haven't finished reading the article yet. I am a fan of Svelte, though, and have switched to using it by default for new projects - coming from a React background.

Up to date data - https://krausest.github.io/js-framework-benchmark/2025/table... - shows Ripple, Vue, and Svelte as some of the best performers.

It is not that popular anymore, tho. At least there is no hype, it is just a bureaucratic soulless tool used by many. The posts about the new React Foundation have almost no engagement here in HN. 5 years ago it would be a huge discussion. Now nobody cares.

that's a lot of data! I've never even heard of Ripple!

> Angular, for example, always walks through the entire component tree

Angular has OnPush change detection strategy and can even be free of zone.js now, so this isn't necessarily true.
