Imaginary Numbers should be built in like Python

[7fe]

I propose we support Imaginary Numbers like Python. The other parts of the proposals are fine with me.

let n = 1j * 1j

you could even support the dot syntax

n.real;
n.imaginary;

Right now JS is rather ignored for computational software compared to let's say Python because it lacks proper imaginary number support(and fractions.)
