Thanks a lot man, thanks a lot. I was frustrated when I was unable to delete the document from my database. The console always threw an exception 'guns is not defined'. guns was the name of my collection. I searched everywhere and my code was looking good, even my course instructor used the same syntax and it worked well on her system but on mine it didn't work. Then I added db.guns.deleteMany
and it worked.
Thanks Man.
