title: Merge Array of Objects
body: <p>I need to merge arrays of objects in browserside javascript like this:</p>
  
  <pre><code>[
    {name: "john", age: 10},
    {name: "doe", age: 14}
  ] 
  </code></pre>
  
  <p>--> new data arrives</p>
  
  <pre><code>[
    {name: "pete", age: 88},
    {name: "larry", age: 42}
  ]
  </code></pre>
  
  <p>should become</p>
  
  <pre><code>[
    {name: "john", age: 10},
    {name: "doe", age: 14}, 
    {name: "pete", age: 88},
    {name: "larry", age: 42}
  ] 
  </code></pre>
  
  <p>Well thats simplified the arrays will contain hundreds of larger objects. Therefore I need a performant solution.</p>
  
  <p>Thanks in advance yours skeec</p>
