| 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]] »). |
