 | |
| 
 | |
|     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.

 | |
| 
 | |
|     DestructuringAssignmentTarget : LeftHandSideExpression
 | |
| 
 | |
|     - It is a Syntax Error if LeftHandSideExpression is either an ObjectLiteral or an ArrayLiteral and if LeftHandSideExpression is not covering an AssignmentPattern.
 | |
|     - It is a Syntax Error if LeftHandSideExpression is neither an ObjectLiteral nor an ArrayLiteral and AssignmentTargetType(LeftHandSideExpression) is not simple.

|     1. Let iteratorRecord be ? GetIterator(value).
 | |
|     2. Let result be IteratorDestructuringAssignmentEvaluation of AssignmentElementList with argument iteratorRecord.
 | |
|     3. If iteratorRecord.[[Done]] is false, return ? IteratorClose(iteratorRecord, result).
 | |
|     4. Return result.

 | |
| 
 | |
|     1. If DestructuringAssignmentTarget is neither an ObjectLiteral nor an ArrayLiteral, then
 | |
|       a. Let lref be the result of evaluating DestructuringAssignmentTarget.
