Assuming I have a tag where values are changed commonly on my page, example:
<p id="valor"></p>
What I have to do in javascript without jquery to listen to this change all the time and perform an action with each change?

Correction of comment, DOMSubtreeModified was depreciated with the new builder MutationObserver()
you can start here:
var observer = new MutationObserver(callback);
take a look at the mozila link https://developer.mozilla.org/en-US/docs/Web/API/MutationObserver/MutationObserver
Refe II: https://developer.mozilla.org/en-US/docs/Web/API/MutationObserver
Ref III: https://developer.mozilla.org/en-US/docs/Web/Events/DOMSubtreeModified
