We build every production codebase in TypeScript by default — ask us why if you're still deciding.
| Feature | TypeScript | JavaScript |
|---|---|---|
| Type safety | Strong static typing catches errors early | No static typing, errors surface at runtime |
| Learning curve | Additional concepts to learn | Lower barrier to entry |
| Tooling and IDE support | Excellent autocomplete and refactoring support | Good, but less precise without types |
| Team scalability | Easier to maintain as team and codebase grow | Harder to maintain consistency at scale |
| Build complexity | Requires a compilation step | Runs natively without compilation |
