checking out mdn documentation on shadow dom

https://developer.mozilla.org/en-US/docs/Web/Web_Components/Shadow_DOM

Basic Shadow DOM example doesn't work in firefox - 

      // create shadow DOM on the <p> element above
      var shadow = document.querySelector('#hostElement').createShadowRoot();

results in console error -  .createShadowRoot() is not a function.

I included webcomponents.js script from Polymer and then shadow dom works fine.

createShadowRoot() is an old API that we're not going to implement in Firefox. The standard one we're working on is tracked in bug 1205323.
