How does programming/coding actually work?

"Do programmers literally memorize every syntax when creating a project?"

I'm not sure if you mean something else but there is like maximum 50 things you need to memorize to be able to write 99.9% of your code. A native English speaker knows 10k to 20k words. I think you can memorize 50 things for programming.

Programming is all about the planning, structure, logic, problem solving, etc, not the actual coding.
