@ttsc/lint - I made 20x faster TS Lint by building it into typescript-go — one compile catches both

TL;DR A typical TypeScript project runs tsc for type checking, then runs eslint again for code style. @ttsc/lint collapses those two steps into a single compile pass . Lint violations come out as plain compile errors. It's built on typescript-go (the next-generation TS compiler rewritten in Go, about 10x faster than legacy tsc ), and reuses the AST the compiler already builds — so there is no extra parsing cost . Combine "two steps into one" with "JavaScript moved to Go," and you get about 20x f
