Methods

ownPropertyNames

ownPropertyNames(cb)

See Object.getOwnPropertyNames

obj.ownPropertyNames(function(err, names) {
  console.log("first own property:", names[0]);
})

ownPropertyDescriptor

ownPropertyDescriptor(name, cb)

See Object.getOwnPropertyDescriptor. Callback gets an object with properties: configurable (boolean), writable (boolean), enumerable (boolean), and value (a primitive or JSObject).

obj.ownPropertyDescriptor('foo', function(err, descriptor) {
  console.log("foo has value", descriptor.value);
})

ownProperties

ownProperties(cb)

Get all the properties of the object and not its prototype. Callback gets an object keyed on property name with property descriptor objects as values.

obj.ownProperties(function(err, properties) {
  for (name in properties) {
    console.log(name + ": " + properties[name].value);
  }
})

prototype

prototype(cb)

Get the prototype object of this object. See Object.prototype. Callback gets the prototype as a JSObject

obj.prototype(function(err, prototype) {
  prototype.ownPropertyNames(function(err, names) {
    console.log("prototype properties:", names);
  })
})
