Is hands on practice more important than theory in web development?

Some courses spend a lot of time explaining concepts, while others dive directly into building small applications. When I looked at one Full Stack Course in Pune, I noticed they push practical sessions from day one.

This made me wonder: how much theory is really necessary before you start building something? Did you understand better when you read documentation first or when you tried coding and learned through errors?

I personally grasp concepts faster when I experiment, but I’m curious how others approached learning. Does focusing too much on theory slow down progress, or does it prevent future confusion?
