Does TypeScript support namespace?

Question

As in the title: does TypeScript support namespaces? If so, how do I use them?

Answer 1

False...

module A.B.C {
    export var x = 1;
}

is equal to

module A {
    export module B {
        export module C {
            export var x = 1;
        }
    }
}

because you can write outside the module A :

var y = A.B.C.x;

But :

module A {
    module B {
        module C {
            export var x = 1;
        }
        var y = C.x; // OK
    }
    //var y = B.C.x; // Invalid
}
//var y = A.B.C.x;   // Invalid
