Battles with false positives in static analysis of JavaScript web applications in the wild

Now that HTML5 technologies are everywhere from web services to various platforms, assuring quality of web applications becomes very important. While web application developers use syntactic checkers and type-related bug detectors, extremely dynamic features and diverse execution environments of web applications make it particularly difficult to statically analyze them leading to too many false positives. Recently, researchers have developed static analyzers for JavaScript web applications addressing quirky JavaScript language semantics and browser environments, but they lack empirical studies on the practicality of such analyzers.
