Indeed, the klipse plugin has access to DOM elements. What ideas do you have for kids? I have tried to do something for kids here: kids.klipse.tech The klipse plugin concept is explained in details: 1. http://blog.klipse.tech&#x2

As far as I know, this is the first time one can experiment the Y combinator in the browser in a live an interactive environment. Feedbacks and comments are appreciated.

The Y combinator is one of the most beautiful idea in Computer Science: it allows to write recursive functions without using names at all!

This article is part of a mini-course for kids about LISP and Clojure. The particularity of this mini-course is that the code snippets are interactive. The snippets are powered by klipse: https://github.com/viebel/klips

In javascript (1, eval) returns eval. But this is indirect. This is why `eval` runs in the outer scope. The whole point of this article is to demonstrate how weird is `eval`.

Every javascript developer knows that eval is evil. But eval is really powerful and from a theoretical perspective eval is very interesting. For instance, did you ever ask yourself in what context does eval run? This article features live &

For kids alone, it is indeed difficult. But if the parent knows a bit about Lisp and goes over the tutorial with them, the kids can learn and even enjoy!

It's still work in progress. Only a few articles for the moment. I would be happy to hear your thoughts about the best way to teach functional programming to kids.
