I listened to the lecture well. There were some inconveniences while listening to the lecture, but I learned a lot nonetheless. I didn't have any major problems listening to the lecture even though I didn't have any prior knowledge of MongoDB or NodeJS. I think it would be a little helpful to find typos and other problems if the source code was provided. I'm looking forward to the instructor's other lectures. I'll go buy the instructor's MongoDB lecture ^_^ I'm already excited to think about the project I'll create using the knowledge I learned through this lecture.
