description: IteratorClose is called when reference evaluation produces an abrupt completion (AssignmentExpression)
esid: sec-variable-statement-runtime-semantics-evaluation
features: [Symbol.iterator, destructuring-binding]
flags: [generated]
info: |
VariableDeclaration : BindingPattern Initializer
1. Let rhs be the result of evaluating Initializer.
2. Let rval be GetValue(rhs).
3. ReturnIfAbrupt(rval).
4. Return the result of performing BindingInitialization for
BindingPattern passing rval and undefined as arguments.
ArrayAssignmentPattern : [ Elisionopt AssignmentRestElement ]
[...]
5. Let result be the result of performing
IteratorDestructuringAssignmentEvaluation of AssignmentRestElement with
iteratorRecord as the argument
6. If iteratorRecord.[[done]] is false, return IteratorClose(iterator,
result).
AssignmentRestElement[Yield] : ... DestructuringAssignmentTarget
1. If DestructuringAssignmentTarget is neither an ObjectLiteral nor an
ArrayLiteral, then
a. Let lref be the result of evaluating DestructuringAssignmentTarget.
b. ReturnIfAbrupt(lref).
