I ran ordered query for insertMany(one provided in handouts:insertMany-ordered.js).
In lecture video, instructor’s query resulted in insertion of 2 documents, with rest three not inserted as error occurred at third document.
Running same query in my case didn’t insert any document.
On some anaylsis, I found that first document itself got into error because in previous lecture(Creating Documents: insertOne)) we had inserted similar document.
People may get confused here. So please add to the video about deleting the document from previous lecture.
