Types and interfaces in TypeScript are tools used to define the shape of data, and each has specific use cases and capabilities. While interfaces define contracts for objects, types offer more flexibility, allowing for union types, conditional types, and more. Interfaces support declaration merging and extending other interfaces, but types are preferred for complex type manipulations due to advanced features. In many scenarios, the choice between the two can depend on personal preference.
