title: Angular - Use map operations like merge, put and delete on a simple object
body: <p>I have an object in angular 5, like this one:</p>
  
  <pre><code>public obj1 = {
      A: 5,
      B: false,
      C: 'c'
  };
  </code></pre>
  
  <p>And another one:</p>
  
  <pre><code>public obj2 = {
      A: 10,
      E: true,
      D: 'd'
  };
  </code></pre>
  
  <p>How can I merge these two object, or delete one of these object properties ?
  I need to do <code>Map</code> operations over this simple object.</p>
  
  <hr>
  
  <p><strong>Update:</strong></p>
  
  <p>I need a way, if there is, to cast this simple object into a <code>Map</code>. </p>
