Better Together: Rust & TypeScript
summary
Argues that specific Rust ideas improve TypeScript by showing working code: a real "friends of user" refactor, a hand-rolled Result-style error type in TypeScript, and comparisons to Go returning value plus error. Demonstrates that treating errors as first-class alternative paths prevents whole-site crashes, eases retry logic, and makes tests simpler. Recommends strict TS config, composition over inheritance via traits-like composition, and favoring pure functions to make large JS codebases more maintainable.
