title: How to combine arrays using javascript
body: <p>How can I combine test1 and test2 to get the same result as test?
  I found concat() and join() can do the combination but can't get the result I want.</p>
  
  <pre><code>  var test1 = [1,5,7,4]
      var test2 = ["apple","banana","apple","banana"]
      var test = [
         {xValue:1,yValue:"apple"},
         {xValue:5,yValue:"banana"},
         {xValue:7,yValue:"apple"},
         {xValue:4,yValue:"banana"}
      ]
  console.log(test);
  console.log(test1);
  console.log(test2);
  </code></pre>
  
  <p>I have 21 arrays with hundreds of length for each one in my real case. I am trying to combine them together and get the result like the example above. 
  Thanks!!</p>
