Is TypeScript worth it?

Short summary

TypeScript is worth adopting for any production codebase beyond throwaway scripts, offering compounding benefits in refactoring confidence, self-documenting code, editor tooling, and compile-time bug prevention. The costs — learning curve, upfront friction, and tooling complexity — are front-loaded and shrink as fluency grows. Teams should adopt gradually by enabling loose settings first, converting core files, and tightening strict mode over time rather than attempting a big-bang rewrite.

• •TypeScript's structural benefits (refactoring, autocomplete, bug prevention) compound with codebase and team size
• •Costs are front-loaded: learning curve, type annotations, and build tooling friction drop sharply after initial adoption
• •Adopt gradually — start with loose settings, convert core data models first, enable strict mode when ready
