title: adjusting the object result Javascript
body: <p>I have two objects. First object old object. Second object new object. As a result I want to combine these objects. How do I go the easy way.
  Example:</p>
  
  <pre><code>// old object
  {
    name: 'exapmle name',
    surname: 'example surname',
    number: '123456'
  }
  
  
  // new object
  {
    name: 'change name',
    surname: 'change surname',
    number: null
  }
  
  // result 
  {
    name: 'change name',
    surname: 'change surname',
    number: '123456'
  }
  </code></pre>
