title: how to merge two arrays into a object using lodash
body: <p>I am looking for best ways of doing this. 
  I have two arrays:</p>
  
  <pre><code>key = [1,2,3];
  value = ['value1', 'value2', 'value3']
  </code></pre>
  
  <p>The end result I want is an array of map:</p>
  
  <pre><code>[{key: 1, value: 'value1'} ,{key: 2, value: 'value2'}, {key: 3, value: 'value3'}]
  </code></pre>
  
  <p>How do I do it the most efficient/clean way using lodash? 
  Thanks! </p>
