We've had a long journey. Main thing is that I realized that my son doesn't learn enough from open ended tools like Scratch. So we tried a bunch of other things.

He started with Scratch JR & Scratch.

Then we switched to Tynker Jr & Tynker. Which provide challenge oriented block based games. Teaches loops, functions, etc.

Then we switched to CodeMonkey, which provides challenge oriented block & code based games (coffeescript, python). Teaches variables, arrays, etc.

Then I felt there was not enough new learning from the above. So I gave him VSCode and had him go through Khan Academy's HTML lesson.

That's when he made a bunch of HTML pages you see: https://www.armaansahni.com/ (pokemon, bakis, etc). ALL the HTML/CSS on the site is hand written.

Then I wanted him to learn how to be resourceful... for this, I gave him a serious of small challenges (eg: "make a function that displays hello world on the screen") where he had to figure out the answer himself. Use Gemini or Google, etc. But don't ask me. He ended up learning how to use Gemini to accelerate his learning (see his blog post, he writes about it a bit) and he was submitting solutions to me in JS. He had prior Gemini experience because he was using it to create images, and JS was natural extension of HTML.

Then one day he decided he wanted to make a game that he had in his mind.

In this above process, I basically observed what he was learning and switched to apps where I felt he could still learn something new.
