💅 The HTML report got an overhaul. We've internally switched from bootstrap to @tailwindcss. This means that we gained a lot of flexibility. Don't you just LOVE the new look? 😻
The HTML reporter is open-sourced separately, so you can use it can be reused by other frameworks.

🧑 Can you write unit tests for SQL now?
🧔 Not SQL, but TSQL.
🧑 And that's different from SQL?
🧔 Yes, it's a full language.
🧑 Including unit tests?
🧔 Yes. You can write your entire application there. If you hate the life you will get pretty far

🤯🤯 Template literals in #TypeScript types to have type matching for strings! This blew my mind 🤯🤯
Is there any other type system that can do this?
🤯😈🤯 Type Recursion with #TypeScript 🤯😈🥲. I can't wait to share the resource with you that I learned this from! (Not finished yet).
