14. If module.[[PendingAsyncDependencies]] is > 0, set module.[[AsyncEvaluating]] to true.

15. Otherwise, if module.[[Async]] is true, perform ! ExecuteAsyncModule(module).

|
16. Otherwise, perform ? module.ExecuteModule().

ExecuteAsyncModule ( module )
|
|
|
|
1. Assert: module.[[Status]] is "evaluating" or "evaluated".
|
|
2. Assert: module.[[Async]] is true.
|
|
3. Set module.[[AsyncEvaluating]] to true.
|
|
4. Let capability be ! NewPromiseCapability(%Promise%).
|
|
5. Let stepsFulfilled be the steps of a CallAsyncModuleFulfilled function as specified below.
|
|
...
|
|
8. Let stepsRejected be the steps of a CallAsyncModuleRejected function as specified below.
|
|
...
|
|
11. Perform ! PerformPromiseThen(capability.[[Promise]], onFulfilled, onRejected).
|
|
12. Perform ! module.ExecuteModule(capability).
|
|
13. Return.

ExecuteModule ( [ capability ] )

...
|
|
11. If module.[[Async]] is false, then
|
|
a. Assert: capability was not provided.
|
|
b. Push moduleCxt on to the execution context stack; moduleCxt is now the running execution context.
|
|
c. Let result be the result of evaluating module.[[ECMAScriptCode]].
|
|
d. Suspend moduleCxt and remove it from the execution context stack.
|
|
e. Resume the context that is now on the top of the execution context stack as the running execution context.
|
|
f. Return Completion(result).
|
|
12. Otherwise,
|
|
a. Assert: capability is a PromiseCapability Record.
|
|
b. Perform ! AsyncBlockStart(capability, module.[[ECMAScriptCode]], moduleCxt).
|
|
c. Return.
