title: Maven plugins to analyze javascript code quality
body: <p>Javascript code can be tough to maintain.<br>
  I am looking for tools that will help me ensure a reasonable quality level.<br>
  So far I have found <a href="https://github.com/pivotal/jsunit" rel="noreferrer">JsUNit</a>, a very nice unit test framework for javascript. Tests can be run automatically from ant on any browser available.<br>
  I have not found yet some javascript equivalent of PMD, checkstyle, Findbug...<br></p>
  
  <p>Do you know any static code analysis tool for javascript ? </p>
