Learning a new language — the basic syntax etc — takes time is you’ve never done it before. Being good enough at it so that you can build an application on your own or as part of a team takes longer.
My daughter is learning to code now — she’s teaching her self — and I want to encourage her. But I also want her expectations to be realistic. I want her to understand that coding isn’t just putting little boxes with code snippets into a graphical web GUI.
I want her to be wary of hyperbolic claims about learning to code and becoming a developer in just a few weeks.
