What does the "Basic" part here mean?

Orginally we named the nodes BasicNode to avoid clashing with the web browser api Node and to distinguish from the Nodes used in NVL. Here we don't have that problem, so I'll drop the basic part for now

This check looks like it isnt needed. Do you think it makes the code clearer/gives a worthwhile optimization, or what do you think about removing it and instead having a test like:
test('should not break on empty bolt records', () => {
const { nodes, relationships, limitHit } = extractUniqueNodesAndRels([]);
if (
nodes === undefined ||
relationships === undefined ||
limitHit === undefined
) {
throw new Error('Invalid return values on empty array of paths');
}
expect(nodes.length).toBe(0);
expect(relationships.length).toBe(0);
expect(limitHit).toBe(false);
});

I added a test similar to this now, thanks 👍
