Theo Ported TypeScript to Rust with AI and Never Read the Code

Theo Browne published a Rust rewrite of the TypeScript compiler and admitted, in the README, that he has never read a line of the code. His own words: I've never read a line of this code.

  • Theo Browne created ts-rust, a Rust rewrite of TypeScript compiler without reading original code
  • $420,000 spent on API tokens for porting process, could have been $20,000
  • ts-rust 13x faster than tsc on VS Code, passes 181,711 Go tests at half the time
