AsyncGeneratorMethod :
|
|
async [no LineTerminator here] * PropertyName ( UniqueFormalParameters )
|
|
{ AsyncGeneratorBody }
|
|
|
|
1. Let propKey be the result of evaluating PropertyName.
|
|
2. ReturnIfAbrupt(propKey).
|
|
3. If the function code for this AsyncGeneratorMethod is strict mode code, let strict be true.
|
|
Otherwise let strict be false.
|
|
4. Let scope be the running execution context's LexicalEnvironment.
|
|
5. Let closure be ! AsyncGeneratorFunctionCreate(Method, UniqueFormalParameters,
|
|
AsyncGeneratorBody, scope, strict).
