What are the advantages of TypeScript over JavaScript? How does it contribute to type safety and the development process? Should a beginner like me make the switch to TypeScript?

TypeScript's biggest advantage is type safety—this allows you to catch and fix errors during the compilation phase rather than at runtime. It significantly contributes to keeping the codebase stable, especially in large teams or big projects. Additionally, with modern IDEs (like VS Code, WebStorm, etc.) supporting TypeScript, refactoring becomes much more reliable and faster—thanks to features like autocompletion and error hints, you save time and minimize human errors.
Personally, I switched to TypeScript in my Vue.js projects, and the feedback has been very positive—especially when working with large teams, as type definitions make it easy to share interfaces or function signatures. If you're a beginner and your projects are likely to grow, switching to TypeScript can help you avoid type-related chaos early on; plus, if you already know JavaScript, the learning curve is quite smooth.
