db.ilists.find()

{ "_id" : ObjectId("5efb10f25372d01d549954b2"), "name" : "click + to add items to the list", "__v" : 0 }
{ "_id" : ObjectId("5efb10f25372d01d549954b3"), "name" : "<---click the checkbox to deletet item in the list", "__v" : 0 }
{ "_id" : ObjectId("5efb170a32b1290c64950999"), "__v" : 0 }
{ "_id" : ObjectId("5efb17790d9ff700204c43c2"), "__v" : 0 }

{ "acknowledged" : true, "deletedCount" : 0 } …
