My company's frontend team (comprised mostly of people who believe anything written) jumped the wagon on Bun.
After a few days of working with it, it turned out that Bun isn't really faster in real world scenarios.
This brings up the question - why market it as so much faster then?
Many frameworks and tools market themselves primarily as faster than $otherThing but it won't fix suboptimal code, wrong choices for data structures, silly things like "let's select * and sort in browser". When you remove those mistakes that bad devs make, it turns out node/deno are more than fast enough. What we need is less bloat, more engineering and no lazy development by "packagemanager install lib-that-could-do-my-work"
