MongoDB insertOne is not a function [solved]

I try to execute "InsertOne" but it come up a error to say"InsterOne of dbname is not a function"

The reason is my mongodb version is too old . InertOne is new in mongoDB 3.4

db.collection.insertOne()

New in version 3.2.

Inserts a document into a collection.

Solution is to upgrade to Mongodb 3.4
