delete operator can be used to remove a
property from an object. It will remove a property from the object if it has one. It
will not touch any of the objects in the prototype linkage.
Removing a property from an object may allow a property from the prototype linkage to shine through:
another_stooge.nickname // 'Moe' // Remove nickname from another_stooge, revealing // the nickname of the prototype. delete another_stooge.nickname; another_stooge.nickname // 'Curly'
