Get number of items returned by last node

To get the number of items returned by the previous node:

JavaScript

if (Object.keys(items[0].json).length === 0) {
return [
	{
		json: {
			results: 0,
		}
	}
]
}
return [
	{
		json: {
			results: items.length,
		}
	}
];

The output will be similar to the following.

[
	{
		"results": 8
	}
]
