Show HN: TJS, The World's Fastest and Most Accurate JSON Schema Validator

Hi HN!

I built TJS over my holiday as a way to experiment and get better at agentic coding. I was astounded at how quickly software can be built when you have a full test spec like JSON Schema has.

The thing I'm most proud of is the TypeScript type inference. It automatically deduces the types from the JSON Schema. Try it out in the playground to see what I mean! https://sberan.github.io/tjs/#playground
