Why would rewriting Claude code, an app which probably has 30-40 (I might be significantly underestimating) extremely active contributors be easier than rewriting Bun, which has fewer contributors and almost certainly also less lines of code?
I'm doubtful that it has fewer lines of code, but even so, it is almost certainly less tricky and simpler code. You could also rewrite it in a higher level and more forgiving language than Rust (e.g. Go) and get huge improvements. The improvements would probably be much bigger than the improvements they have achieved at the JavaScript runtime level.
I don't think people are saying it's easier, they're saying the results would be better.
this. /s
Because I’ve been told that Fable can do anything :-)
My question is moreso “why was it ever JS in the first place”
& the cost of a native rewrite would be cheaper than acquiring Bun no matter how you shake it
