説明

It would be useful when a module can implement an interface using the implements keyword. Syntax: module MyModule implements MyInterface { ... }.

Example:

interface Showable {
    show(): void;
}
function addShowable(showable: Showable) {

}

// This works:
module Login {
    export function show() {
        document.getElementById('login').style.display = 'block';
    }
}
addShowable(Login);

// This doesn't work (yet?)
module Menu implements Showable {
    export function show() {
        document.getElementById('menu').style.display = 'block';
    }
}
addShowable(Menu);
