Resolve multiple imports through a for await loop in an async generator

esid: sec-finishdynamicimport

info: |
|

Runtime Semantics: FinishDynamicImport ( referencingScriptOrModule, specifier, promiseCapability, completion )
|

|
|
2. Otherwise,
|
|
a. Assert: completion is a normal completion and completion.[[Value]] is undefined.
|
|
b. Let moduleRecord be ! HostResolveImportedModule(referencingScriptOrModule, specifier).
|
|
c. Assert: Evaluate has already been invoked on moduleRecord and successfully completed.
|
|
d. Let namespace be GetModuleNamespace(moduleRecord).
|
|
...
|
|
f. Otherwise, perform ! Call(promiseCapability.[[Resolve]], undefined, « namespace.[[Value]] »).
