You just can't have an app that downloads external code and then runs it; if all of the code that gets run is prepackaged in the app bundle or user-generated then it's absolutely fine.

Are browsers exempt? Because there are a few of them there, and they download and execute external JavaScript.

Yes, but they may do so only by embedding Apple's own sandboxed WebKit component. So the downloading, execution, and results are tightly controlled.

I believe all browsers in the app store that run js use Apple's UIWebView and don't run the js themselves.

[kemiller → dmitshur]

They have to use Apple's JS engine.

I thought those were running interpreters via javascript. User-generated code is really okay?
