NeDB data update and download, will it fail?

Question

JavaScript

When updating data, NeDB does not overwrite the data, but creates a new row.
Won't it happen that NeDB selects a row with stale data when it reads it? It looks like this.

{"log":"red","pass":"fff","unitg":{"id":null,"x":5,"y":5},"_id":"vTujNu7XuacFl35N"}
{"log":"red","pass":"fff","unitg":{"id":null,"x":10,"y":5},"_id":"vTujNu7XuacFl35N"}
{"log":"red","pass":"fff","unitg":{"id":null,"x":11,"y":5},"_id":"vTujNu7XuacFl35N"}

So far everything is fine, but I want to know for the future that this will not happen.
