Question

using:

• node.js - version 8.0.0
• neo4j-driver: 1.3.0
• neo4j database: community edition, version: 3.2.0

i am running a cypher (not important what exactly is the cypher) and getting back a result.

after parsing the result using the follwing code:

result.records[0].get('instanceStock').properties

i am getting the following json:

{  
   "quantity":{  
      "low":10,
      "high":0
   }
}

the value 10 is the correct one which actually reside inside the db.

---

1. what is the meaning of the "low" and "high" properties?
2. why the correct answer reside inside the "low" property?
