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.

|
|
AssignmentElement[Yield] : DestructuringAssignmentTarget Initializeropt
|
|
[...] 7. If Initializer is present and v is undefined and
|
|
IsAnonymousFunctionDefinition(Initializer) and IsIdentifierRef of
|
|
DestructuringAssignmentTarget are both true, then
|
|
a. Let hasNameProperty be HasOwnProperty(rhsValue, "name").
|
|
b. ReturnIfAbrupt(hasNameProperty).
|
|
c. If hasNameProperty is false, perform SetFunctionName(rhsValue,
|
|
GetReferencedName(lref)).
