The author shares two small TypeScript utility functions that implement Rust's Result pattern, converting exceptions into typed Result values (Ok/Err) instead of relying on try/catch blocks. The article explains Rust's Result<T, E> enum and the ? operator before demonstrating how to bring similar error-handling discipline into TypeScript projects.
Background
Rust's Result type is a core language feature that enforces explicit error handling by requiring callers to deal with both success and error cases. TypeScript developers familiar with Rust often seek ways to bring similar type-safe error handling into their JS/TS projects.
