Listen and perform action

Assuming I have a tag where values are commonly changed on my page, for example: 

  <p id="valor"></p>

What do I have to do in javascript without jquery to stay listening to this change all the time and take action with every change?

Comment correction, DOMSubtreeModified was deprecated with new constructor MutationObserver() you can start here:

var observer = new MutationObserver(callback);

take a look at the mozila link link
