Most of the books have been low-key attempts from programmer parents, probably to get their own children into programming. They were posted on different forums, and I have a hard time finding my way back to them. The example that I think illustrates my point best is: http://arthur-johnston.com/hacker_writes_a_childrens_book/ http://arthur-johnston.com/hacker_writes_a_childrens_book/ (which was posted here in 2017: https://news.ycombinator.com/item?id=15879519 https://news.ycombinator.com/item?id=15879519) The book works well as entertainment for grown-up programmers: "G is for Garbage Collector/when something's no longer needed/it frees up the memory/so your program is speeded." You can look inside the book on Amazon for more examples. I judge this rhyme as too advanced for any child below 8 that I've read aloud to. Most theories about cognitive development agree with Piaget (1896–1980) in that children have a hard time grasping difficult abstract concepts before the age of 12–13, so there is at least some "scientific backing" to my hunch: https://en.wikipedia.org/wiki/Cognitive_development#Concrete_operational_stage https://en.wikipedia.org/wiki/Cognitive_development#Concrete... (This is only a hunch though; the children I've read aloud to are all picked from the same group – children of family and friends.) My observation is that children seem to need _lots_ of concrete verbal and visual imagery in order to stay interested. You can also get away with more abstract themes if the actual text is lyrically well-crafted, like Dr. Seuss' books (or André Bjerke's children's rhymes in Norwegian, my mother tongue). The most successful attempts at teaching programming to children that I've seen, seem to give the children a lot of practical tasks they can work on (e.g. the Hello Ruby book series). You also have some programming elements in Minecraft that children could pick up, because the concepts are implemented as concrete objects. All of this makes me suspect that the main audience for these "children's books" teaching programming is adults that already know a fair bit about the subject. And that's completely all right by me, because it gives the books traction and brings the book's readers entertainment. PS: You also have the Javascript/HTML/CSS for babies series, which are only jocularly presented as children's books: https://imgur.com/eOYc8fC https://imgur.com/eOYc8fC
