  ContinueDynamicImport ( _promiseCapability_, _moduleCompletion_ )
    1. ...
    1. Let _module_ be _moduleCompletion_.[[Value]].
    1. Let _loadPromise_ be _module_.LoadRequestedModules().
    1. Let _rejectedClosure_ be a new Abstract Closure with parameters (_reason_) that captures _promiseCapability_ and performs the following steps when called:
      1. Perform ! Call(_promiseCapability_.[[Reject]], *undefined*, « _reason_ »).
      1. Return ~unused~.
    1. Let _onRejected_ be CreateBuiltinFunction(_rejectedClosure_, 1, *""*, « »).
    1. Let _linkAndEvaluateClosure_ be a new Abstract Closure with no parameters that captures _module_, _promiseCapability_, and _onRejected_ and performs the following steps when called:
      1. Let _link_ be Completion(_module_.Link()).
      1. ...
      1. Let _evaluatePromise_ be _module_.Evaluate().
      1. Let _fulfilledClosure_ be a new Abstract Closure with no parameters that captures _module_ and _promiseCapability_ and performs the following steps when called:
        1. Let _namespace_ be GetModuleNamespace(_module_).
        1. Perform ! <emu-meta effects="user-code">Call</emu-meta>(_promiseCapability_.[[Resolve]], *undefined*, « _namespace_ »).
        1. Return ~unused~.
