Question

Is there any method for when been called an object it returns a field of that object?

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

// Instead of "n.v", I would want to use "n" directly
if (n.v == 10) { console.log("ok") }

Answer 1

var n = new Int16(10); will set n to a reference to an object of your Int16 type.

What you’re looking for may be to set the valueOf and toString functions to return the value of v.
