How can I learn to code without knowing coding?
The fact is: you can’t learn to code by reading about it. The only way to learn is by actually coding. Don’t worry about learning the wrong thing. Any language that you pick will at least help you learn the concepts central to programming.
Is it normal to make mistakes on a computer?
Probably lots of them. Screwing up is normal, and you need to have the attitude that it’s ok to make mistakes. As you see more and more error messages, you’ll eventually start to become better and better at deciphering what they mean and how they can help you solve problems.
