The templates are being used for many tests reusing the same available function forms. The format they are provided allow us to extend tests with cases for other tests relying in the same formats.

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).
