If thisArg is omitted, mapfn is called with the global object as the
this-value in sloppy mode
info: |
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.
iii. Let _thisValue_ be _globalEnv_.[[GlobalThisValue]].
