Good defaults make a difference! Here's @sveltejs and SvelteKit: Great perf, SSR, minimal JS for interactivity, file-based routing, build-time optimizations baked in (w/@vite_js). A lot to like :) kit.svelte.dev
ALT 99/100 Lighthouse score for this Svelte application. FCP is 1.6s, LCP 1.6s, TTI 1.6s, TBT 0ms.

So what did we learn about tech interviews?
- They resemble the gold standard stress test in psychology studies
- They are severely inequitable and biased, especially towards women and other under represented groups
- They bare almost no resemblance to our day to day jobs

Interviewing in tech is broken (especially whiteboard interviewing). Let's talk about it and back it up with ✨research✨ from a team of researchers at NC State and Microsoft in this paper titled 'Does Stress Impact Technical Interview Performance?'

Thinking of converting your project to #TypeScript? ⌨️
@hartzis tried it with react-swipeable and had some learnings AND success. 🚀
Here’s what went well and what you can look out for:

Thank you @FormidableLabs for prioritizing and allocating time for open source contributions!
👆 react-swipeable v6.0.0 published! 🎉
Highlights:
- TypeScript: entire codebase converted
- Removed <Swipeable> component; only exports a react hook now: useSwipeable
- Decreased bundle size by 0.6 kb min+gzip

After a month of work, I'm proud to announce the first public release of Fielder!
It's a form library which breaks the mould by using a field-first, dynamic approach to forms and validation (goodbye big ol' yup schemas) 👋💯🚀

One of the most important lessons I've learned as a developer joining new teams constantly (consultancy), is to not assume I have the ideas to "fix" all the code problems after one week of coding.
