A vaguely Lispy language in the context of JavaScript.
The Evan language is implemented by means of an evaluator, which transforms any JSON into a JavaScript value. Often, this is again JSON but it can also be React DOM elements which are then rendered into a browser.
The evaluation is in principle functional, in the sense that evaluating the same piece of JSON leads to the same result.
Also, the evaluation is wired to happen incremental (using mobx), so (small) changes to the JSON input should only require a partial re-evaluation for better performance.
The main goal of the Evan programming language is to bootstrap a working, functional-style general purpose programming language which nestles comfortably in the JavaScript-world, complete with tools like an IDE.
It also ports selected virtues of a number of existing languages (most notably: Lisp) to the context of JavaScript.
The IDE should (eventually) be implemented as an Evan program itself, making it meta-circular.
To get started with development, clone this repository and run npm install or yarn, or whatever :)

As you've probably already noticed, the "Evan" acronym is awkward. That's because is retrofitted to the name of Meinte's first-born :)
