Just experimenting with publishing a package

function inOrderArray(root) {
	if (!root) return [];

	return [...inOrderArray(root.left), root.val, ...inOrderArray(root.right)];
}

function postOrderArray(root) {
	if (!root) return [];

	return [...postOrderArray(root.left), ...postOrderArray(root.right), root.val];
}

module.exports = {
	inOrderArray,
	postOrderArray
};
