Developing with Nix

This has been moved to the Matrix AI blog: https://matrix.ai/2018/03/24/developing-with-nix/

Note that if you just to compile a simple C program, and you don't want to fiddle with environments:

nix-shell --packages stdenv

// A: is this pure function?
function sum(a, b) { return a + b }
// B: is this a pure function?
const k = 2
function addK(a) { return a + k }
// C: is this a pure function?
function sub(a, b) { return sum(a, -b) }
// D: is this a pure function?
function sub(a, b, summer) { return summer(a, b) }
// E: is this a pure function?
