Pros

Catch errors at compile time
Better IDE support and autocomplete
Improved code documentation
Easier refactoring

Cons

Initial setup overhead
Learning curve for type system
Slightly more verbose code

Our Verdict:

TypeScript for large applications and teams, JavaScript for small projects

Introduction

TypeScript adds static typing to JavaScript, providing better tooling and catching errors early. Here's when it makes sense to switch.

When to Use TypeScript

Large codebases with multiple developers
Complex applications with many interdependencies
Long-term projects that need maintainability
When you want better IDE support

When JavaScript is Fine

Small projects and prototypes
Quick scripts and one-off tasks
When you need maximum flexibility

Conclusion

TypeScript is increasingly becoming the standard for professional web development. Start with JavaScript, but consider TypeScript as your projects grow.
