| TypeScript | VS | JavaScript |
|---|---|---|
| JavaScript with static types. Catches errors at compile time and improves IDE tooling. | The dynamic language of the web. No type system, maximum flexibility, runs everywhere. |
TypeScript
Pros
- Catches bugs at compile time
- Better IDE autocompletion
- Self-documenting code
- Safer refactoring
Cons
- Steeper initial learning curve
- More verbose type annotations
- Build step required
JavaScript
Pros
- No type system overhead
- Instant feedback loop
- Runs everywhere natively
- Simpler mental model
Cons
- Runtime errors are common
- Harder to maintain large codebases
- Less IDE support for refactoring
- No compile-time checks
Verdict
TypeScript is the better choice for teams and large projects. JavaScript remains great for small scripts and rapid prototyping.
When to use which
Use TypeScript for team projects, large codebases, and anything you'll maintain long-term. Use JavaScript for quick scripts, prototypes, and small solo projects.
