title: Expected ')' to match '(' from instead saw while running the JSHint
body: <p>I am using the d3 library to draw a path/line, for this I need to use <strong>stroke-dasharray</strong> property as given below. </p>
  
  <p>This works fine for me, </p>
  
  <pre><code>vis.append("path")
     .attr("class", "predictedLowerCI")
     .attr("d", valueline5(scope.rowdata))
     .attr({ 'stroke-dasharray': (2, 2) })
  </code></pre>
  
  <p>When I run JSHint, I get the following error </p>
  
  <blockquote>
    <p>"Expected ')' to match '(' from line 194 and instead saw ','." </p>
  </blockquote>
  
  <p>where I have used <strong>stroke-dasharray</strong>. The error comes for this syntax <code>(2, 2)</code>, basically <code>JSHint</code> does not seem to like this syntax of d3. Is there way to tell JSHint this is a valid syntax? </p>
