Get number of items returned by the previous node

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

JavaScriptPython

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
	}
]

if len(items[0].json) == 0:
	return [
		{
			"json": {
				"results": 0,
			}
		}
	]
else:
	return [
		{
			"json": {
				"results": items.length,
			}
		}
	]

The output will be similar to the following.

[
	{
		"results": 8
	}
]
