Delete several nodes in Neo4j

Question

I have an array of multiple IDs of nodes to delete. Every Cypher example I can find either deletes one node or all nodes. How would one delete nodes that match an array of IDs, in a single query?

Something like this... (pseudocode):

MATCH (n:Node) WHERE (n.id in ['id_a', 'id_b']) DELETE n;

You can use the IN list operator:

If id is a property:

WITH [1,2,3,4] AS ids
MATCH (n) WHERE n.id IN ids
DETACH DELETE n;

If by id you mean the internal node id:

WITH [1,2,3,4] AS ids
MATCH (n) WHERE id(n) IN ids
DETACH DELETE n;
