title: Create an observable from an Object along with a starting value
body: <p>I am creating an angular v4 app. I have the following data.</p>
  
  <pre><code>currentCount={
  name:'myName',
  count:0
  };
  </code></pre>
  
  <p>Here the user will change the above object with the relevant data. I want to create an observable out of this object so that whenever there is a change I can save(process) the data.
  Also, I want to pass the default data when the observable is subscribed to.</p>
  
  <p>As I am a starting out with RXjs I feel lost. </p>
  
  <p>Any help is appreciated.</p>
