This has been a long time coming, but I hope the finished product was worth the wait.

ArkType 2.0 is a no-setup solution for schema validation with a new style of type-safe API that parallels native type syntax.

It also brings types to runtime in a way they've never been available before. They can be introspected and compared just like `extends` in native TS.

Thanks for your patience, and I couldn't be more hyped to see what you do with it!

What exactly is ArkType? What problem does it solve? Is it for typescript? Vanilla JavaScript?

It does runtime validation like Zod.

It can be used in vanilla JS but usually it is used with TypeScript for all the same reasons people normally use TypeScript.
