 Once you are comfortable with basics and syntax, the next step is projects. I use a 10-line program that solves a common problem for me — adding `body { text-align: justify }` to `epub` files that are not justify aligned. I didn't know that this line would help beforehand, I searched online for a solution and then automated the process of unzipping `epub`, adding the line and then packing it again. That will likely need you to lookup documentation and go through some stackoverflow Q&A as well. And once you have written the solution and use it regularly, you'll likely encounter corner cases and features to be added. I feel this is a great way to learn and understand programming.
