will the app store reject my app if I use a javascript sdk for the backend? : <p>I'm using Trigger.io to make an app I can deploy to both the app store and google play. 
I'm researching baas backends that offer native sdk's for android and apple, but also offer javascript sdk's which I assume are meant for things like Trigger or Phonegap. 
My question is do the app store guidelines favor one kind of back end service over another? Is javascript risky for backend? I just want to be sure before I pay for a service. The services I'm considering are cloudmine and shephertz. </p>
