Start doing the same thing you will regularly as a programmer. Pick a tool chain, download whatever tooling is required, get the tutorial project up and running. Next, start making changes. Use the tutorial project as a template to fundamentally build some kind of site/tool/app. Encounter barriers, Google and GPT your way to solving those problems. Start adding features and functionality. Rinse and repeat until you know enough to be dangerous. At this point you are now a "programmer".
