Here lies the internal methods for ordinary objects.
Most objects make use of these methods, including exotic objects like functions.
So thats why this is a trait https://tc39.es/ecma262/#sec-ordinary-object-internal-methods-and-internal-slots

Required methods

fn get_own_property(&self, prop: &Value) -> Property

https://tc39.es/ecma262/#sec-ordinary-object-internal-methods-and-internal-slots-getownproperty-p The specification returns a Property Descriptor or Undefined. These are 2 separate types and we can't do that here.

fn set_prototype_of(&mut self, val: Value) -> bool

https://tc39.es/ecma262/#sec-ordinary-object-internal-methods-and-internal-slots-setprototypeof-v

fn define_own_property(&mut self, property_key: String, desc: Property) -> bool

fn get_internal_slot(&self, name: &str) -> Value

Utility function to get an immutable internal slot or Null

fn set_internal_slot(&mut self, name: &str, val: Value)

fn insert_property(&mut self, name: String, p: Property)

fn remove_property(&mut self, name: &str)
