Hey gang, in this tutorial I’ll be showing you how we can use update operators to change our data. In particular, we’ll take a look at the increment operator. Find a full list at:

  1. Could someone clarify for me how the following works: we update the name to Luigi and we're still able to grab onto Mario and increment his weight; Robo shows the Mario record with an incremented weight, yet the Luigi update test also passed but there is no Luigi to be found. Thanks for your reply.

  2. I think there is a little misconception about how you check the updated weight. By using update operator you are assuming that, every record might have different than initially value, but then you just assert it with static value. What you could do is checking it with value of objects found before the incrementation
