Description: The ‘Mapped Type’ in TypeScript is a powerful feature that allows transforming the properties of one type into another. This functionality is based on TypeScript’s ability to dynamically manipulate types, facilitating the creation of derived types from existing ones. By using ‘Mapped Types’, developers can create new types that reflect or modify the properties of an original type, resulting in greater flexibility and code reuse. This technique is particularly useful in situations where there is a need to adapt a type to meet specific requirements, such as creating types that only include certain properties or that change the type of existing properties. Mapped types are defined using the mapped type syntax, which allows iterating over the properties of a type and applying transformations to each of them. This not only improves code readability but also helps maintain consistency and integrity of types in large and complex applications. In summary, ‘Mapped Type’ is an essential tool in TypeScript that enables developers to create more precise and tailored types to their needs, thus facilitating the development of robust and scalable applications.
