title: merge two arrays (keys and values) into an object
body: <p>Is there a common Javascript/Coffeescript-specific idiom I can use to accomplish this? Mainly out of curiosity.</p>
  
  <p>I have two arrays, one consisting of the desired keys and the other one consisting of the desired values, and I want to merge this in to an object.</p>
  
  <pre><code>keys = ['one', 'two', 'three']
  values = ['a', 'b', 'c']
  </code></pre>
