LexicalBinding : BindingPattern Initializer
|
||
|
|
|
||
|
|
1. Let rhs be the result of evaluating Initializer.
|
||
|
|
2. Let value be GetValue(rhs).
|
||
|
|
3. ReturnIfAbrupt(value).
|
||
|
|
4. Let env be the running execution context's LexicalEnvironment.
|
||
|
|
5. Return the result of performing BindingInitialization for BindingPattern
|
||
|
|
using value and env as the arguments.
