Return the value of the property whose key is _propertyKey_ from this object. If any ECMAScript code must be executed to retrieve the property value, _Receiver_ is used as the *this* value when evaluating the code. <ins>If this operation is to be performed from within an `unsafe` block, _unsafe_ will be *true*; otherwise, _unsafe_ will be *false*.</ins>

Set the value of the property whose key is _propertyKey_ to _value_.

<p>DRAFT NOTE: Except where specified, it is assumed that existing invocations of [[Get]] or [[Set]] that do not currently pass a value for the _unsafe_ parameter are assumed to pass *false*. These call sites will be updated when the fully integrated specification text becomes available during Stage 2.</p>
