    If the construct trap is not set, propagate the construct to the target object.

    5. Let trap be ? GetMethod(handler, "construct").
    6. If trap is undefined, then
      a. Assert: target has a [[Construct]] internal method.
      b. Return ? Construct(target, argumentsList, newTarget).
    ...

    GetMethod ( V, P )

    ...
    3. If func is either undefined or null, return undefined.
