N-Queens Puzzle

I have decided to write a solution to the N-Queens Puzzle, one of the classic problems in computer science, in the AEC programming language. That puzzle asks in how many ways you can arrange n chess queens on an n-times-n chessboard without breaking the rules that no two chess queens can be in the same row, column or diagonal.
This only works in very modern browsers. I'm not too interested in targeting archaic browsers here. This only works in Firefox 62 and newer or Chrome 69 and newer. After a few years (if not months), all JavaScript environments will become as capable as they are, rather than like Internet Explorer.
