alt Hacker NewsAll the best to them, however this feels like yah shaving instead of focusing into delivering a browser than can become an alternative to Safari/Chrome duopoly.

Javascript is a self contained sub system, if the public API stays the same, then they can rewrite as much as they want, also I suppose this engine now will attract new contributors that will want to contribute to Ladybird just because they enjoy working with Rust.
Don't forget that the Rust ecosystem around browsers is growing, Firefox already uses it for their CSS engine[0], AFAIK Chrome JPEG XL implementation is written in Rust.
So I don't see how this could be seen as a negative move, I don't think sharing libraries in C++ is as easy as in Rust.
Maybe it is my cynicism, but I always suspect such projects to be endless rabbit chasing. It is not about catching it.
Agreed. They said they ruled out rust in 2024, I believe the article they published was near the end of 2024 because I remember reading it fairly recently.
Seems like a lot of language switches in a short time frame. That'd make me super nervous working on such a project. There will be rough parts for every language and deciding seemingly on whims that 1 isn't good enough will burn a lot of time and resources.
think of it as axe sharpening rather than yak shaving
Part of browser experience is safety and migrating their JS library to Rust is probably one of the best ways to gain advantage over any other existing engine out there in this aspect. Strategically this may and likely will attract 3rd party users of the JS library itself, thus helping its adoption and further improving it.
They're not porting the browser itself to Rust, for the record.
