Types Vs Interfaces In Typescript. Type nullish = null | undefined; You should use types by default until you need a specific feature of interfaces, like 'extends'. Differences between types and interfaces. The easiest difference to see between type and interface is that only type can be used to alias a primitive: Interfaces can't express unions, mapped types, or conditional. Importantly, there is no discernible performance difference between types and. Type fruit = 'apple' | 'pear' | 'orange';. They are very similar, and for the most. Types and interfaces are used to define custom data structures and shapes, but. Types offer predictability and are less likely to exhibit unexpected behavior. Types are favored for primitive values, union/intersection types, functions and tuples, while interfaces offer better error messages and type checking. Being concerned only with the structure and capabilities of types is why we call typescript a structurally typed type system. There are two main tools to declare the shape of an object:
