This is the first time you have made a new lecture. I trust you and I think I can trust and take the next Views and Firebase lecture. Thank you for your hard work. By the way, in the first or second lecture, you introduced Python's local web server and said that there is a difference because Python is not installed by default on Windows. If you have to install npm to install firebase-tools anyway, I think you could have introduced the default local web server as npm's lite-server instead of Python so that you can use the same functions on Windows and Mac. The instructor looked very tired from the lecture, but please don't push yourself too hard. I will look forward to the Views and Firebase lecture ^^
