Runtime Semantics: Evaluation

|
|
|
ImportCall : import . source ( AssignmentExpression )
|
|
1. Return ? EvaluateImportCall(AssignmentExpression, source).
|
|
|
|
13.3.10.1.1 EvaluateImportCall ( specifierExpression, phase )
|
|
1. Let referrer be GetActiveScriptOrModule().
|
|
2. If referrer is null, set referrer to the current Realm Record.
|
|
3. Let specifierRef be ? Evaluation of specifierExpression.
|
|
4. Let specifier be ? GetValue(specifierRef).
|
|
5. Let promiseCapability be ! NewPromiseCapability(%Promise%).
|
|
6. Let specifierString be Completion(ToString(specifier)).
|
|
7. IfAbruptRejectPromise(specifierString, promiseCapability).
|
|
8. Let moduleRequest be a new ModuleRequest Record { [[Specifier]]: specifierString, [[Phase]]: phase }.
|
|
9. Perform HostLoadImportedModule(referrer, moduleRequest, empty, promiseCapability).
|
|
10. Return promiseCapability.[[Promise]].

16.2.1.7.2 GetModuleSource ( )
|
|
Source Text Module Record provides a GetModuleSource implementation that always returns an abrupt completion indicating that a source phase import is not available.
|
|
1. Throw a SyntaxError exception.
