Enum as Parameter in TypeScript

Question

Isn\'t it possible to set the type of a parameter to an Enum? Like this:

private getRandomElementOfEnum(e : enum):string{
    var length:number = Object.         


        

Answer 1

You can do better than any:

enum E1 {
    A, B, C
}
enum E2 {
    X, Y, Z
}

function getRandomElementOfEnum(e: { [s: number]: string }): number {
    /* insert working implementation here */
    return undefined;
}

// OK
var x: E1 = getRandomElementOfEnum(E1);
// Error
var y: E2 = getRandomElementOfEnum(window);
// Error
var z: string = getRandomElementOfEnum(E2);
