constructor.name is undefined in Internet Explorer

Question

My debugging work in IE ended today by finding that constructor.name is undefined.

I created the following simple code that reproduces the issu

Answer 1

I wrote this for my needs (acknowledging it may not be full-proof):

if (!Object.constructor.prototype.hasOwnProperty('name')) {
    Object.defineProperty(Object.constructor.prototype, 'name', {
        get: function () {
            return this.toString().trim().replace(/^\S+\s+(\w+)[\S\s]+$/, '$1');
        }
    })
}

The regex being performed in the method is making an assumption that the 2nd non-whitespace group of characters IS the name of the constructor. This is a viable solution for the code that I'm working with, while this may not be full-coverage for all others' needs.
