You have full JS support inside UIWebView. You can inject your own JS code and communicate with the existing JS code.

According to the policy set by Apple on applications for the iPhone, you can not use any interpreted language. Thus, Javascript is unfortunately out of the question.

This is stated in the iPhone SDK agreement.

3.3.2 — An Application may not itself install or launch other executable code by any means, including without limitation through the use of a plug-in architecture, calling other frameworks, other APIs or otherwise. No interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s).

Continuing with what Michael Kessler said you can also use javascript embedded in a UIWebView to access native iPhone functionality via libraries such as phoneGap making your javascript more powerful than the normal safari variety.

Includes a iPhone project that you can use as a basis for your javascript application.
