|
||
|
|
[...]
|
||
|
|
3. When the FunctionDeclaration f is evaluated, perform the following steps
|
||
|
|
in place of the FunctionDeclaration Evaluation algorithm provided in
|
||
|
|
14.1.21:
|
||
|
|
a. Let fenv be the running execution context's VariableEnvironment.
|
||
|
|
b. Let fenvRec be fenv's EnvironmentRecord.
|
||
|
|
c. Let benv be the running execution context's LexicalEnvironment.
|
||
|
|
d. Let benvRec be benv's EnvironmentRecord.
|
||
|
|
e. Let fobj be ! benvRec.GetBindingValue(F, false).
|
||
|
|
f. Perform ! fenvRec.SetMutableBinding(F, fobj, false).
|
||
|
|
g. Return NormalCompletion(empty).
