Dev String says:

thank you. THANK YOU!!!!

I’ve been learning to code already for a good while, and I was trying to figure out how to simply get some data from API, but every tutorial i watched or documentation I read, i got confused. I just got lost and started thinking that I don’t know anything and that I’m just not good at all this. This just proves that it’s all about the way you teach, and that most people just are bad at it, even though they might be good programmers. You’ve earned a subscription!
