I'm very excited about the prospects of Signals being added to the ECMA standard. The readme provides a great read: github.com/proposal-signals/…
I've opened a (small) issue there about "effects", feel free to upvote if you agree with it: github.com/proposal-signals/…

“To avoid loading too much JavaScript, Wiz only loads the code required by interactive components” -- sounds like Angular is going the server components route to me 🤷🏻♀️ blog.angular.io/angular-and-…

I wish there was a way to easily copy the @tseslint rule name to add an override in my `rules` config. @JoshuaKGoldberg, what do you think about this? 😏

I'm very excited about getting our mutant operator naming proposal merged. If you're implementing a mutation testing framework, why not align on this naming convention? (Yes, admiditly, I'm a bit of a nerd 🤓) github.com/stryker-mutator/m…

The most egregious JSDoc example I've seen is non-null type assertions (postfix-!). The JSDoc equivalent is incredibly verbose.
So it's surprising that "types-via-JSDoc" is so popular. Folks use it despite the verbose syntax. For them, the no-build juice is worth the squeeze.
