It's a real shame that this didn't get more discussion because the author raises some good points that would benefit from heated debate. Bun is insanely good. Its single greatest victory is papering over the CJS/ESM nightmare with an "it just works" approach. The speed improvements result in a qualitatively different DX (especially for TS projects) that can feel like a religious experience for how profound the impact can be. And still, the issues raised in this post stand.

> But here we are with the worst templating system, JSX and the most contentious of all frontend tooling, TypeScript built in to Bun.

So, the author has some strong opinions that they seem to hold as universal.
