Mapped types are a feature in TypeScript that allows for the creation of new object types by iterating over keys of existing types. This blog post explores the mechanics of mapped types, focusing on their primary use cases in transforming object types and mapping tuples. By demonstrating how properties can be selected and transformed—particularly in converting synchronous interfaces to asynchronous ones—the article highlights the practical applications of this feature, showcasing examples and providing deeper insights into its functionality.
Mapped types allow developers to create new object types by iterating over properties, providing a powerful tool to transform and map existing types in TypeScript.
By utilizing mapped types, developers can efficiently convert synchronous interfaces into asynchronous ones, illustrating the versatility and practicality of this feature for type manipulation.
