Damian’s notes

Microsoft’s TypeScript is the latest JavaScript infrastructure project to rewrite in Go or Rust for the sake of speed. Microsoft have opted for Go. It will be funny if Go’s biggest user group turns out to be TypeScript programmers.

A runtime for TypeScript or JavaScript programs that is positioned as a single-executable alternative to TypeScript + Babel + Node + NPM + ESLint + Prettier + Webpack. Modules are imported from URLs (same system as ES6 modules running in browsers), and asynchronous APIs use promises rather than those old-fashioned callbacks (so not a drop-in replacement for Node). Implemented in Rust, and aiming to be secure-by-default by restricting access to files and networks unless explicitly allowed.
