Description: In TypeScript, an interface type is a structure that defines a contract for objects, specifying what properties and methods must be present. This allows developers to create objects that adhere to this structure, ensuring consistency and predictability in the code. Interfaces are fundamental in TypeScript as they provide a way to type objects more precisely than primitive types. By defining an interface, one can specify not only the data type of each property but also whether they are optional or can be of a specific type. This helps prevent common runtime errors, as TypeScript can perform type checks at compile time. Additionally, interfaces can be extended, allowing for the creation of type hierarchies and efficient reuse of definitions. In summary, interfaces in TypeScript are a powerful tool for creating more robust and maintainable code, facilitating collaboration among developers and improving code readability.
