humidityHistory.add(temp); ... Woops!

[@undencem]

Best working Observer Pattern example and up-to-date . Thanks

[@UpTown430]

Perfect explanation. Everything is so clear, thank you 👌

[@BeABetterDev]

Glad it helped!

[@vihangafernando6644]

To be honest, your video helped me to understand RXJS. As they have been using observer pattern.Thanks.

[@kAreezArsalan]

That was truly amazing, such a wonderful explanation with code... loved it.

[@haciendadad]

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.

[@BeABetterDev]

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.

[@BeABetterDev]

You're very welcome!

[@juandavidlopezlopez8079]

The explanatory ability of this video is amazing. Thank you!

[@BeABetterDev]

Thanks so much for your kind words Juan, and I'm glad you enjoyed!

[@Hyp3rX360]

excellent series I've found, I have the book but you explain it very good. Thanks for your work!

[@eamonsuen]

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

[@giocruzx]

Congratulations on the video! Your way of teaching is very good!

[@BeABetterDev]

Thank you! 😃

[@ma3435]

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 =)

[@AP-eh6gr]
