ArkType is TypeScript's 1:1 Validator | David Blass | Ep 35B 1:09:53

לפני 13 hours1:09:53

1:09:53

David Blass ( @ssalbdivad.dev ) teaches the two fools about ArkType and its 1:1 validator type system. If you, like us, thought ArkType was only about validation, think again! David pulls back the curtain on what makes ArkType unique, how he built a type-level parser to provide helpful error messages, and why ArkType can provide soundness guarantees that go beyond even what vanilla TypeScript can offer. *waves hand* These are the array intersections you're looking for.
