Hey HN, I recently came across a very useful tutorial about jq (https://earthly.dev/blog/jq-select/) and created an interactive tutorial based on it. It features a command-line sandbox where you can safely explore and run arbitrary jq commands (it runs jq in your browser using WebAssembly).

Check it out if you want to learn how to filter, process, and wrangle JSON data. And if you happen to be getting started in bioinformatics, check out the rest of the tutorials on sandbox.bio :)

Can you just compile arbitrary programs to work in web assembly now? This is super cool!

Thanks! It's generally easiest to do for C/C++/Rust/AssemblyScript code (other languages often need to ship things like garbage collection or an interpreter alongside it). But even with those languages, it's not always trivial to support features in the browser like file systems, threads, SIMD, etc.
