Answer
insertOne inserts a single document. insertMany inserts multiple documents in one operation and improves performance.
Quick Answer
insertOne() inserts a single document and returns the inserted document's _id. insertMany() inserts an array of documents in one operation - faster than calling insertOne() in a loop (one network round-trip). insertMany() by default stops on first error (ordered mode). Set {ordered: false} to continue inserting remaining documents even if some fail.
