A more readable and annotated version of the Javascript groupBy from Ceasar Bautista (https://stackoverflow.com/a/34890276/1376063)

	var groupBy = function(data, key) { // `data` is an array of objects, `key` is the key (or property accessor) to group by
	// reduce runs this anonymous function on each element of `data` (the `item` parameter,
	// returning the `storage` parameter at the end
	return data.reduce(function(storage, item) {
	// get the first instance of the key by which we're grouping
	var group = item[key];

	// set `storage` for this instance of group to the outer scope (if not empty) or initialize it
	storage[group] = storage[group] \|\| [];
