2. Let currentContext be the running execution context.
|
|
3. Let originalEnv be the VariableEnvironment of currentContext.
|
|
4. Assert: The VariableEnvironment and LexicalEnvironment of currentContext
|
|
are the same.
|
|
5. Assert: environment and originalEnv are the same.
|
|
6. Let paramVarEnv be NewDeclarativeEnvironment(originalEnv).
|
|
7. Set the VariableEnvironment of currentContext to paramVarEnv.
|
|
8. Set the LexicalEnvironment of currentContext to paramVarEnv.
|
|
9. Let result be the result of performing IteratorBindingInitialization for
|
|
BindingRestElement using iteratorRecord and environment as the
|
|
arguments.
|
|
10. Set the VariableEnvironment of currentContext to originalEnv.
|
|
11. Set the LexicalEnvironment of currentContext to originalEnv.
