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.

2. If iteratorRecord.[[done]] is true, let v be undefined.
|
|
3. If Initializer is present and v is undefined, then
|
|
a. Let defaultValue be the result of evaluating Initializer.
|
|
b. Let v be ? GetValue(defaultValue).

4. Return the result of performing BindingInitialization of BindingPattern
|
