TypeScript vs. JavaScript: Differences and use cases for each

TypeScript and JavaScript have distinct advantages for different project needs. JavaScript excels in quick prototyping and small projects, while TypeScript offers static typing and advanced tooling for large-scale applications and team collaboration. A fintech startup example demonstrated TypeScript's ability to reduce runtime failures by 70% after a costly JavaScript bug. Key differences include TypeScript's compile-time error catching, improved maintainability, and enhanced object-oriented programming support. The choice between them depends on project complexity, team size, and long-term goals.
