✂️ My stance re. coding agents in Knip repo in short:
- Added AGENTS.md
- Coding agents are fine, but take responsibility and don't cause unnecessary review and "wall of text" overhead
- Vibe-coded PRs may be rejected without explanation

This isn't just a plugin to show unused exports. It offers a unique way to view & navigate your code and connect the dots. Feels like there's so much potential here.
Excited for you to try out the preview! 🙏

✂️ Knip v5.71.0 is out
With improvements & quite the refactor to support the upcoming language server and IDE extensions
What I want to highlight today though, is continued support for Node 18, TypeScript 5.0 and CommonJS. Useful for legacy projects and e.g. migration to modern ESM syntax

It’s been a very hard year - Andy Bell
Unlike a lot of places in tech, my company, Set Studio/Piccalilli has no outside funding. Bootstrapped is what the LinkedIn people say, I think. It’s been a hard year this year. A very hard year...

We've talked about this before: `gh pr co` is nice but doesn't add the remote. So here's a little script to check out someone's PR and push your changes to it:
```
gh-pr-co
...git wild & commit...
gh push pr
```
Or is there a better way?
Gist: gist.github.com/webpro/7d49e...

Interestingly, Array.from(set) with mapper arg is twice as slow (compared to spread/Array.from().map) in Node. In Bun it's faster.
Passing in an [] is much faster than a set (but each item still has to be copied over). Here, Node is faster.
Only in rare cases should you worry about this, I'd say.
