What is TypeScript type compatibility?

What is TypeScript type compatibility?

TypeScript type compatibility is a way to determine if one type can be assigned to another. It focuses on the structure of types rather than their names.

Can you give me an example of type compatibility?

Sure! If you have a type Animal with a property name, and a type Dog that extends Animal, a Dog can be assigned to an Animal type because it has the same structure.

What about function type compatibility?

Function type compatibility in TypeScript is based on the parameter types and return types. A function can be assigned to another if its parameters are compatible and its return type is the same or a subtype.

Are there any common pitfalls with type compatibility?

Yes, one common pitfall is assuming that two types are compatible just because they have the same properties. TypeScript checks for structural compatibility, so it's important to consider the context.
