Consider `listAllProperties`

[dotproto]

MDN has a simple method to get all properties on an object here.

function listAllProperties(o) {
  var objectToInspect
  var result = [];

  for(objectToInspect = o; objectToInspect !== null; objectToInspect = Object.getPrototypeOf(objectToInspect)){  
    result = result.concat(Object.getOwnPropertyNames(objectToInspect));
  }

  return result;
}
