As codebases grow, maintainability becomes the bottleneck. See how TypeScript's type system acts as a guardrail for large teams.
## Safety at Scale
JavaScript is flexible, but that flexibility becomes a liability in large systems. TypeScript adds a layer of safety that catches errors at compile time, not runtime.
### Refactoring with Confidence
Imagine renaming a core interface property. In JS, you grep and pray. In TS, you rename symbols and the compiler guides you to every usage.

Invest in your types, and your future self will thank you.
