# When To Use TypeScript - A Detailed Guide Through Common Scenarios

**[Khalil Stemmler](https://daily.dev/sources/khalilstemmler)** · 15 min read · 0 upvotes · 0 comments

## Summary

A practical guide examining when TypeScript is worth adopting over vanilla JavaScript. The author categorizes hard software problems into three types — performant systems, embedded systems, and complex domain problems — arguing TypeScript is most essential for complex domain problems where large codebases and team size make type safety critical. Key decision factors covered include codebase size, production vs. pet projects, team size, startup context, and framework choice (React vs. Angular). The guide also demonstrates how TypeScript better communicates design patterns like the Abstract Factory through abstract classes, interfaces, and access modifiers. Concludes with advice on gradual TypeScript adoption and its value for leveling up software design skills.
