Can interfaces extend other interfaces in TypeScript?
Yes, in TypeScript, interfaces can extend other interfaces. This allows you to create a new interface that inherits properties from one or more existing interfaces.
Can you give me an example of that?
Sure! For instance, if you have an interface Person
with properties like name
and age
, you can create another interface Employee
that extends Person
and adds a property employeeId
.
What happens if there are conflicting properties?
If there are conflicting properties, TypeScript will throw an error. You need to ensure that the properties are compatible or override them in the extending interface.
