What is type compatibility in TypeScript?
Type compatibility in TypeScript refers to how types relate to each other, determining if one type can be assigned to another.
Can you give me an example of type compatibility?
Sure! If you have a type Animal
and a type Dog
that extends Animal
, a Dog
can be assigned to a variable of type Animal
.
Are there any exceptions to type compatibility?
Yes, there are exceptions, such as when using incompatible types like string
and number
, which cannot be assigned to each other.
How does structural typing affect type compatibility?
Structural typing means that TypeScript checks the shape of types rather than their explicit declarations, affecting compatibility.
