    You did a really good job explaining this in a clear and easy metaphor that can easily be pictured. Seeing something in your mind makes it easy to remember! Also, I have a copy of that book, it is the ABSOLUTE best for learning, everyone is an image I can easily picture and this remember.

      Thanks so much Joey, your comment means a lot to me! I completely agree with you that the visual approach is such a powerful way to learn. Its part of the reason I started making these videos. Being a visual learner myself, I couldn't always find videos on many topics. I hope that my videos can help others that are in a similar situation!
      Thanks again for your support and stay safe.

    Watched a few of the software design pattern videos, and they're all great. Thank you very much for sharing.

    great video! Just going to note that we probably want to use this.humidityHistory.add(humidity) instead of this.humidityHistory.add(temp) in the ForecastDisplay class so it doesn't show the same list :D

    Its frustrating how university professors are just scrolling down and reading a pdf file on zoom without showing examples and explaining this way . they believe they are doing a good job but they are just useless they are getting paid for nothing ... Thank you very much for the explanation =)
