I notice that Chrome gives me a "Reference Error: this is not defined" 
such that (alert("hello 1");) never gets called in your constructor:
______________________________
constructor(re, im) {
         alert("hello 0");
         this.re = re;
         alert("hello 1");
         this.im = im;
     }
______________________________

I must be creating (ComplexRect) objects in a totally screwed up way:
______________________________
{
    var c = new ComplexRect(-.75, .09);
    alert(c.re + ", " + c.im);
}
______________________________

How do I create instances of (ComplexRect)?

I need to think here.

Because I like to add on extra components for fun/experimental purposes. ;^)

Also, take a look at my (ct_complex_roots) function:
_________________________________________
function ct_complex_roots(c, p)
{
    var l = ct_complex_abs(c);
    var s = Math.pow(l, 1.0 / p);
    var a = Math.atan2(c[1], c[0]) / p;

    var n = Math.ceil(Math.abs(p));
    var as = (Math.PI * 2) / p;
    var roots = [];

    for (var i = 0; i < n; ++i)
    {
        roots.push([Math.cos(a + as * i) * s,
                    Math.sin(a + as * i) * s]);
    }

    return roots;
}
_________________________________________


The return value from this can contain more than two objects, so, IMVHO, 
the ease of iterating the return value (roots) is very nice wrt Arrays.
