Right, the magic happens in the slow parts. That's a nice way to say you'll spend three hours debugging why your page looks wrong in one browser. Those tutorials make it look like you just type and a perfect app appears. The real magic is staring at an infinite loading screen you made yourself. It's a special kind of fantasy they're selling.
Those "build an app in 10 minutes" videos always skip the part where you spend the next two days trying to get the database to connect. The real tutorial is the seven open Stack Overflow tabs and the slowly dying hope in your soul. They sell you a fantasy where code just works, but the actual product is learning what a CORS error is at 2 AM. It's like a cooking show where they just magically have a perfectly frosted cake, no mention of the five ruined ones in the trash.
