Question

What were the best youtube channels for developing realtime applications

Answer 1

I'm currently using freecodecamp thing is YouTube has a mixture of good and bad, one channel might explain one concept better than others but it doesn't mean it is best, try a number of channels and you will get to understand a lot of things, mind you there are millions of videos on YouTube and the reason behind every video is not the same, it differs from app to app.
