tsx - run typescript code

https://github.com/privatenumber/tsx

Features

• Blazing fast (ed: 🙄) on-demand TypeScript & ESM compilation
• Works in both CommonJS and ESM packages
• Supports next-gen TypeScript extensions (.cts & .mts)
• Hides experimental feature warnings
• TypeScript REPL
• Resolves tsconfig.json paths

I'ved used ts-node for small stuff, and it works... fine. tsx uses esbuild instead of tsc, so it should be faster but also it doesn't typecheck.
