initialiseKeys.js

var initialiseKeys = function initialiseKeys (obj) {
  var val
  for (var key in obj) {
    val = obj[key]
   
    // the key isn't 'init' BUT it's an object we need to explore it
    if (key !== 'init' && typeof val === 'object') {
      initialiseKeys(val)
    // hey the key is 'init' and its value is a function!
    } else if (key === 'init' && typeof val === 'function') {
      obj.init()
    }
  }
