What are some common type errors in programming?

Common type errors include type mismatches, null reference errors, and incorrect type casting. Would you like examples?

Yes, please provide examples of type mismatches.

A type mismatch occurs when an operation is performed on incompatible types, like adding a string to an integer. For instance, in Python, 5 + 'hello' will raise a TypeError.

What about null reference errors?

Null reference errors happen when you try to access a property or method on a null object. For example, in Java, calling myObject.method() when myObject is null will throw a NullPointerException.

How can I avoid these type errors?

To avoid type errors, use type checking, write unit tests, and leverage static type systems like TypeScript or Flow.
