Less memory consuming by mutate array items:

Suggested change

	return list.map(([lookupIndex, name, params, aliases]) => [
	lookupIndex,
	name,
	params,
	aliases.slice(1).filter((a) => !dupes.includes(a))
	]);
	return list.map((item) => {
	item[3] = item[3].slice(1).filter((a) => !dupes.includes(a))
	return item
	});
