|
ArrayBindingPattern : [ Elisionopt BindingRestElement ]
|
|
1. If Elision is present, then
|
|
a. Let status be the result of performing
|
|
IteratorDestructuringAssignmentEvaluation of Elision with
|
|
iteratorRecord as the argument.
|
|
b. ReturnIfAbrupt(status).
|
|
2. Return the result of performing IteratorBindingInitialization for
|
|
BindingRestElement with iteratorRecord and environment as arguments.
