Wrote another piece on manipulating AST, this time round is less focused on @babeljs , but more generic techniques on manipulating ASTs lihautan.com/manipulating-as…

ECMAScript excitement 😉 PRs to Babel now run against test262 - the official JS conformance test suite. This raises quality and helps ensure users can migrate from transpiled to native feature usage smoothly. Congrats to @jbhoosreddy @NicoloRibaudo @JLHwung @r_ricard

Wrote up a tracking issue if you have ideas since we added test262 to @babeljs CI! 🌐 UI to see failing tests + determine priority 📊 Find out discrepancies b/t browsers and make fixes for preset-modules 📄 Better document loose/spec behavior via tests github.com/babel/babel/issue…

Next.js, Babel, Parcel, Svelte, and others mentioned as early adopters of GitHub Actions 🚀

Houssein just announced something I've been working on for a little while: @babel/preset-modules! A Babel preset that enables native async/await, Tagged Templates, arrow functions, destructured and rest parameters, and more - in 88% of browsers. github.com/babel/preset-modu…

Wohooo!! Another release in @babeljs in which I could help with a little feature. I really enjoy learning from this project. I highly recommend everyone looking for first-time contribution to look at the issue tracker, you'll find many interesting things. 🚀🎉🤓

Gave a small talk at FB in NY today (rather clickbait title I know)! Thanks @aarondjents for reaching out Just talking life: why I quit my job, day to day, what I've been up to, maintenance as more than code, money/fundraising, interdisciplinary reading, and personal struggles!

Ok I should of mentioned this earlier but excited to be in the Bay Area for 2 weeks starting Monday! (anyone else going to GH Universe/CDS?) Also looking to chat with any companies that are looking to sponsor Babel or other open source projects; happy to give a talk too!

Here is another good first issue of @babeljs . github.com/babel/babel/issue… This issue is on the type inferrer in traverser, one of babel's core components. Feel free to leave a comment if you would like give it a try.

No custom syntax, no transform plugin. You should @babeljs macros instead 😀 lihautan.com/babel-macros/

Heading out to DC for @The_Maintainers unconf this week, who else is coming or in the area (or dm)? I'll be leading a session on the importance of our practices (vs just code) in the development and maintainance of process knowledge. Can probably a lot of great podcast guests!

test262 CI work is also coming along: github.com/babel/babel/pull/… According to @NicoloRibaudo, we are passing 53,169/69,345 tests, at 77% (might say more about what code ppl write). Other engines: - Chakra: 66% - JSC: 81% - SpiderMonkey: 87% - V8: 90% - Moddable XS: 91%
