14.7 Async Arrow Function Definitions
|
|
|
|
AsyncArrowFunction :
|
|
...
|
|
CoverCallExpressionAndAsyncArrowHead => AsyncConciseBody
|
|
|
|
AsyncConciseBody :
|
|
{ AsyncFunctionBody }
|
|
|
|
...

|
|
|
Supplemental Syntax
|
|
|
|
When processing an instance of the production AsyncArrowFunction :
|
|
CoverCallExpressionAndAsyncArrowHead => AsyncConciseBody the interpretation of
|
|
CoverCallExpressionAndAsyncArrowHead is refined using the following grammar:
|
|
|
|
AsyncArrowHead :
|
|
async ArrowFormalParameters
|
|
|
|
|
|
14.1.19 Runtime Semantics: IteratorBindingInitialization
|
|
|
|
FormalsList : FormalsList , FormalParameter
|
|
|
|
1. Let status be the result of performing IteratorBindingInitialization for
|
|
FormalsList using iteratorRecord and environment as the arguments.
|
|
2. ReturnIfAbrupt(status).
|
|
3. Return the result of performing IteratorBindingInitialization for
|
|
FormalParameter using iteratorRecord and environment as the arguments.
