How I Learned to Stop Worrying and Love TypeScript
summary
TypeScript moves code from confusion to clarity by catching contract bugs at compile time; a 2018 survey shows ~46.6% of JS devs have used it and 9 out of 10 would use it again. Concrete examples: converting an NPR One Angular codebase (upgrade toward Angular 5) with allowJs to migrate incrementally, and rebuilding an Alexa skill from scratch using the Alexa SDK with shipped type definitions. Type errors reveal issues like tokens missing refreshToken and force fixes early — type errors are friends.
