Custom value returned by typeof

Question

Is there any way to return a custom type instead of "object"? On the next case, I would want to return i.e. "i16"

>function Int16(v) { this.v=v }; var n = new Int16(10);

>typeof n
"object"
>Object.prototype.toString.call(n)
"[object Object]"

Answer 1

No, you can’t overload typeof — it always returns the base type.

In the given example, you could use the constructor property:

function Int16(v) { this.v=v }; 
> var n = new Int16(10);
> n.constructor.name
"Int16"
> n.constructor === Int16
true
