No more classes only proxy to functional stuff

example.js

/**
 * Functional is always better. Keep it simple, just proxy them to classes if you need
 * Classes sucks. Try to avoid them.
 * Always give a way to use something "class specific" to others
 *  => don't make it class specific in the first place
 * /

function Foo(x) {
  this.x = x;
}

// bad
Foo.prototype.squared = function() {
  return this.x * this.x;
}
// OR
Foo.prototype.squared = function() {
  this.x = this.x * this.x;
  return x;
}

// better
// this lives "somewhere", you have commonjs and amd, deal with it.
function square(x) {
  return x * x;
}

Foo.prototype.squared = function() {
  return square(this.x);
}
// OR
Foo.prototype.squared = function() {
  this.x = square(this.x);
  return this.x;
}
