When I read about the bun rewrite I thought no sh*t, those are the exactly the types of bugs I would expect when doing a line by line rewrite of a program in a GC language to memory managed.
I was unimpressed with the engineering from the blog, and I'm not surprised to read andrew say they claimed no fuzz testing. I know someone who interviewed at bun when it was less than 10 people (around 5 he said). Allegedly jared lowballed the fk out of my friend, claimed they had no money because they're a startup, then proceeded to offer <1% equity
I think I'm missing something; neither zig nor rust are GC languages. Did bun originally start off in javascript or something, and the rewrite you're referring to is from JS to zig?
