When I started using TypeScript, the errors felt overwhelming.
But over time, I realized something important:
TypeScript errors are warnings, not obstacles.
Common TypeScript Errors
Property does not exist on type
This usually means your type definition doesn’t fully match your data.
Type ‘string’ is not assignable to type ‘number’
A classic example of TypeScript saving you from runtime bugs.
Object is possibly ‘undefined’
A reminder to handle edge cases before they reach production.
Implicit ‘any’ type
Explicit types improve readability, maintainability, and team collaboration.
Why This Matters
- Prevents bugs before runtime
- Makes your code safer and more predictable
- Improves long‑term scalability
Type safety > runtime surprises 🚀
If you’re still writing plain JavaScript, TypeScript is one of the best upgrades you can make.
