I love javascript so much

So update: this is valid javascript:

var a = ["", ""].map((_, index) => {
	return [...new Set(b.map((type) => {
		return ([...type][index]);
	}))];
});

where b is any valid 2d array.

This is a part of the Square class of Mendel.js, my genetics npm library (wip).
It’s used to find the parents of a flattened punnet square, which is made using this:

/**
 * @function
 * @arg {Array<*>} arr
 * @description removes duplicates from an array
 */
function deduplicate(arr) {
	return [...new Set(arr)];
}

so that’s what I’m doing now.

too many .map functions to reasonably think about.
