Can you explain 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.
What do you mean by structure of types?
In TypeScript, two types are compatible if their members match. For example, if type A has all the properties of type B, A can be assigned to B.
Can you give me an example?
Sure! If you have a type Person
with properties name
and age
, and another type Employee
that has those plus an employeeId
, then a Person
can be assigned to Employee
if it has the same properties.
What about function type compatibility?
Function type compatibility is similar. A function can be assigned to another if it has the same parameters and return type, allowing for flexible function usage.
