Resolve multiple imports through a for await loop in an async generator yielding imports
|
|
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]] »).
|
|
flags: [async]

features: [dynamic-import, async-iteration]
