👉 The `declare ior` directive in TypeScript is used to import and expose an interface from a module as a public type, allowing other parts of your application to use that interface without needing to import the entire module. This is particularly useful for organizing code into smaller modules, each with its own set of types, and for making those types accessible across different files. By declaring `ior` in this way, you can define the structure of an I/O object or any other type that represents input/output operations, such as reading from a file or network, and make it available to other modules through a single, clear interface. This promotes modularity, reduces coupling, and enhances code maintainability.
