  <p>background:</p>
  
  <p>I was trying to extract all <strong>proto</strong> functions from Array Type. </p>
  
  <pre><code>const arrayProto = Array.prototype 
  const arrayMethods = Object.create(arrayProto) 
  </code></pre>
  
  <p><code>arrayMethods</code> returns <code>Array {}</code></p>
  
  <p>I found all methods are in <strong>proto</strong> (light purple) while none of them is counted.If I change <code>arrayProto</code> to a normal array like [1,2,3], I can get numbers by arrayMethods[i] since all the numbers are listed in <strong>proto</strong>.
  My first thought is that light purple ones are ignored or somehow don't belong to  <code>arrayMethods</code>. However I cannot found any documents about this part of console.
  Why and How to solve it?</p>
