TypeScript.fm - The Friendly Show for TypeScript Developers

Daniel Rosenwasser and Jake Bailey join the two fools to talk about what's coming soon in TypeScript 6 and 7. What changes should developers expect? What might the new compiler API look like? How is the Go port progressing? We talk about smarter (and stricter) defaults, ES targets, module resolution, and why it's hard to emulate JavaScript floating point semantics in Go.
