And astexplorer.net can help you prototype that rule.

Basically it is like JSFiddle but for code transformations and lets you prototype plugins for Babel, ESLint, PostCSS and more. If you are new to all this you can watch this talk I recorded last year giuseppegurgone.com/babel-plugin-d…

Impostor syndrome starting to set in 😓 any tips to remedy? Reckon this picture depicts it pretty accurately!?

The monkeylang designed by Thorsten Ball now officially in astexplorer , I am happy 😘

I'm back from a week at my mom's house and now I'm getting ads for her toothpaste brand, the brand I've been putting in my mouth for a week. We never talked about this brand or googled it or anything like that. As a privacy tech worker, let me explain why this is happening. 🧵

And it’s live! You can now play around with Scala 3’s AST using Scalameta in you browser!

Understanding ASTs will give you JavaScript superpowers in the tooling space.

So if you have used the TypeScript playground (typescriptlang.org/play) ... what do you think we are missing? I would love answers from all developer levels! RT Please :)

good news for SWC plugin authors astexplorer.net added support for SWC 🎉 thanks OJ Kwon Donny (강동윤) Felix Kling

If there isn't a good rule for your use case, you can write one. I have seen engineers pull up astexplorer.net for the first time (credit Felix Kling !), and an hour later, they've written their first custom rule with ESLint. It's true joy.

Sourcegraph 4.0 is out! ◆ Code Insights added in the search UI ◆ A faster, simpler search experience ◆ Auto-indexing for precise code nav ◆ Large-scale server-side changes across your code …and much more. srcgr.ph/ue0Da

In 2022 I got into how programming languages work. thanks to Thorsten Ball incredible book - Writing An Interpreter In Go. Now, I've just come across this site astexplorer.net where you can take a look at what the Abstract Syntax Tree of compiled Javascript looks like.

Fighting this trend will affect your career in the most brutal way imaginable. The best, highest paying jobs likely already went all-in on TypeScript **or want to** Having some weird, dumb anti-ts take will increasingly limit yourself to lowest-quality engineering jobs.

Ugh, didn't "quote retweet" the previous retweet. My 2c: Types become increasingly important the more people work on the same codebase.

It's finally here! The first major release of ESLint in almost two years. This took a ton of work by a lot of people, and we couldn't have done it without the support of our sponsors. ❤️🙏
