and https://codecombat.com, which has been around for a while now.

I think this paradigm (navigating a character using "move" function invocations) is good but kind of exhausts its usefulness after a while. I question whether my daughter learns coding this way or just is playing a turn based top down platformer. The most code like thing is when you use 'loops' to have characters repeat sequences of moves. I think when kids grok these things these apps become just types of glofiried education flavoured video games. There are a lot of things in kodable for instance that I feel are just basic web games with coding terms slapped on it.

https://scratch.mit.edu/ is more like 'programming' imo, even at the level of the objective -- having a blank canvas to create something. It seems a little advanced for my kids right now though.

+1 Scratch! My son started with it, then expanded into Roblox/Lua.

Children can download other people's games and experiment there. Scratch also has pre-made art, sounds, music.

Scratch.mit.edu is a highly-recommended place to start [1] https://scratch.mit.edu/

> Scratch is the world’s largest coding community for children and a coding language with a simple visual interface that allows young people to create digital stories, games, and animations. Scratch is designed, developed, and moderated by the Scratch Foundation, a nonprofit organization. [2]

Someone who uses scratch.mit.edu (like me)

Now that I think of it, I did start game development on scratch before going right into java (because of minecraft).

I'm looking for the best systems to help a 4/5 year old get the basics of programming. My daughter has shown interest in what I do, and loves puzzles and building things. Looking for something visual and fun that can start her down the path of logic and creating with computers.

I have a passing familiarity with Scratch [1], which I'm now looking into more, but am hoping others can share their knowledge and experience in this area.

nice one! you can make it even faster by creating a compile time multiplication table as i have done here, so all that happens at runtime is the bucketing of similarly aged fish, 7 multiplications + a sum

you've still got some overhead in your code, my rust solution creates a dense lookup array at runtime & takes ~200us on my 10850k. are you including file IO and printing to stdout?
