Description: A function interface in TypeScript is a structure that defines the parameters and return type of a function. This allows developers to clearly specify how a function’s signature should be, improving code readability and maintainability. By using function interfaces, it can be ensured that implemented functions adhere to a specific contract, helping to prevent errors at compile time. Function interfaces are especially useful in large and complex applications, where clarity in function definitions is crucial for teamwork and collaboration. Additionally, they enable the creation of higher-order functions, where functions can be passed as arguments or returned as results, facilitating functional programming patterns. In summary, function interfaces are a powerful tool in TypeScript that promotes a more structured and safe approach to programming, helping developers create more robust and less error-prone applications.
