Can you think of a way to have this function run in O(1) instead of O(n)?

[RazEfron]

Using the toArray method and comparing the set's length to that of the array

Suggested change

	let currentNode = this.head;
	let dataSet = new Set();
	while (currentNode) {
	if (dataSet.has(currentNode.data)) {
	return true;
	} else {
	dataSet.add(currentNode.data)
	};
	currentNode = currentNode.next;
	};
	return false;
	let arr = this.toArray;
	let dataSet = new Set(arr);
	return !(array.length === dataSet.size);
