title: Add better debug statement to overlay in VS Code
body: <p>I use the library <code>bignumber.js</code>, which does the job of handling big/small numbers very nicely. However, debugging with VS Code is a pain, as i get the following output upon inspection:</p>
  
  <p><a href="https://i.stack.imgur.com/Bo70N.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Bo70N.png" alt="VS Code inspect of bignumber"></a></p>
  
  <p>Is there a way for me to edit this? I've looked into prototype editing but I could not get this to work.</p>
