When I started using TypeScript, the errors felt overwhelming.
But over time, I realized something important:
👉 TypeScript errors are warnings, not obstacles.
Here are some common ones every developer sees:
❌ 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
Each TypeScript error you fix:
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.
