     10  Table 3: Additional Fields of Cyclic Module Records
     11 
     12  [[Async]]
     13 
     14  ...
     15  Having an asynchronous dependency does not make the module asynchronous. This field must not change after the module is parsed.
     16 
     17  Evaluate ( ) Concrete Method
     18 
     19  ...
     20  6. Let capability be ! NewPromiseCapability(%Promise%).
     21  7. Set module.[[TopLevelCapability]] to capability.
     22  8. Let result be InnerModuleEvaluation(module, stack, 0).
     23  9. If result is an abrupt completion, then
     24    ...
     25    d. Perform ! Call(capability.[[Reject]], undefined, «result.[[Value]]»).
     26  10. Otherwise,
     27    ...
     28    b. If module.[[AsyncEvaluating]] is false, then
     29      i. Perform ! Call(capability.[[Resolve]], undefined, «undefined»).
     30    ...
     31  11. Return undefinedcapability.[[Promise]].
     32 
     33  InnerModuleEvaluation( module, stack, index )
     34 
     35  ...
     36  14. If module.[[PendingAsyncDependencies]] is > 0, set module.[[AsyncEvaluating]] to true.
     37  15. Otherwise, if module.[[Async]] is true, perform ! ExecuteAsyncModule(module).
     38  16. Otherwise, perform ? module.ExecuteModule().
     39 
     40  ExecuteAsyncModule ( module )
     41 
     42  1. Assert: module.[[Status]] is "evaluating" or "evaluated".
     43  2. Assert: module.[[Async]] is true.
     44  3. Set module.[[AsyncEvaluating]] to true.
     45  4. Let capability be ! NewPromiseCapability(%Promise%).
     46  5. Let stepsFulfilled be the steps of a CallAsyncModuleFulfilled function as specified below.
     47  ...
     48  8. Let stepsRejected be the steps of a CallAsyncModuleRejected function as specified below.
     49  ...
     50  11. Perform ! PerformPromiseThen(capability.[[Promise]], onFulfilled, onRejected).
     51  12. Perform ! module.ExecuteModule(capability).
     52  13. Return.
     53 
     54  ExecuteModule ( [ capability ] )
     55 
     56  ...
     57  11. If module.[[Async]] is false, then
     58    a. Assert: capability was not provided.
     59    b. Push moduleCxt on to the execution context stack; moduleCxt is now the running execution context.
     60    c. Let result be the result of evaluating module.[[ECMAScriptCode]].
     61    d. Suspend moduleCxt and remove it from the execution context stack.
     62    e. Resume the context that is now on the top of the execution context stack as the running execution context.
     63    f. Return Completion(result).
     64  12. Otherwise,
     65    a. Assert: capability is a PromiseCapability Record.
     66    b. Perform ! AsyncBlockStart(capability, module.[[ECMAScriptCode]], moduleCxt).
     67    c. Return.
