Dave, you are an amazing teacher. I have built an entire ePOS system on my own while studying how to program. Your tutorials on Node and express helped me a lot on building my backend server.

Your teaching are on point and easy to understand. I’m buying you a coffee. Thank you brother

You're a great teacher. You know so well how to convey the intended educational message about an advanced topic in accumulating small digestible chunks, helping one to have a solid understanding why things work this way, not just how.

very informative David! thanks for sharing the content like this

Thanks Dave. Your tutorials are excellent. However, I want to suggest that you demarcate your output when you log it out on the console. So, it would be easy for someone to know what section of the code is being displayed at what section on the console. Outputs on the console can be confusing and diifficult to comphrehend without demarcation.
