title: How can I get the value from an animated or interpolated value in React Native?
body: <p>Short answer is: with <code>addListener</code>.
  Every animated variable has addListener() method accessible. Right?
  We should NOT access it from <code>__getValue()</code>.</p>
  
  <hr>
  
  <p>I was struggling to get the interpolated value (number) out of this const:</p>
  
  <pre><code>const interpolatedvalue = this.state.myanimvalue.interpolate({...})
  </code></pre>
  
  <p>I wanted to get the numeric value out of this <code>interpolatedvalue</code>. I was trying to use __getValue(), but I realized I should not do that. </p>
  
  <p>Please check my answer below and leave comments if you need help.</p>
