If thisArg is omitted, mapfn is called with the global object as the

6. If _mapping_ is *true*, then

a. Let _mappedValue_ be Call(_mapfn_, _thisArg_, « _nextValue_, 𝔽(_k_) »).

OrdinaryCallBindThis, when _F_.[[ThisMode]] is ~global~, where _F_ is the

function object:

6. Else,

a. If _thisArgument_ is *undefined* or *null*, then

i. Let _globalEnv_ be _calleeRealm_.[[GlobalEnv]].

ii. Assert: _globalEnv_ is a Global Environment Record.
