Javascript Cash Withdrawal like Cash Machine

	// function in javascript that performs a withdrawal based on the balance and an array of banknotes available, for example, I need to withdraw 5 reais, and there are notes of 5 notes of 10, 4 notes of 20, 3 of 50, 5 of 100, so it would not have value of 5 reais, and if I withdraw 550 I discount it on the bills and I always do it in the best way possible
	function cashWithdrawal(value, availableNotes) {
	let notes = [];
	let availableNotesOriginal = structuredClone(availableNotes);
	// array com os valores de todas as notas disponíveis
	const allNotesValues = Object.keys(availableNotes).map((note) => Number(note)).sort((a, b) => b - a);
	for (const subsetNotes of subsets(allNotesValues, 0, 2)) {
	let remainingValue = value;
	for (const noteValue of subsetNotes) {
	// quantas notas desse valor eu preciso?
