I tried searching for various things like “typo” and “new menu” before posting this; hope it is not a duplicate!
There is a small typo at 00:34 in the transcript of https://university.mongodb.com/mercury/M001/2021_April_13/chapter/Chapter_1_What_is_MongoDB_/lesson/5f32d54204e9ffbe482e938e/lecture
“A collection would contain new menu documents”
“A collection would contain many documents”
Hope that helps!
