You start software development with "Hello, world!" and then you do more, like getting input from the user, storing it in a variable, then eventually you're using classes and working with objects, then you're tying together a bunch of classes and working with APIs.
No one just "studied" how to create a gas turbine and wah-la, it was made. The entire process of literally everything was one learning exercise after another. We started by using rocks as tools. Here we are, having built better tools from experience and a lot of trial and error and fooling around with things.
