My 2022 Pick: Sandpack
The folks at CodeSandbox open-sourced their ridiculously powerful in-browser bundler, and packaged it up in a world-class embedded code editor. Such an amazing tool!
My 2022 Pick: React Beta Docs
The new React docs are incredibly well-written, accessible for beginners, and beautifully designed. Documentation is one of the hardest things to do well, so this fantastic example is my pick of the year!
