Usage

Open demo

// give me nodelists
var watched = require('watched');
// quick
var foos  = watched('.foo');
// or more specific
var foos2 = watched(document).querySelectorAll('.foo'); // same as watched('.foo')
var bars  = watched(document).querySelector('.bar');
var bazs  = watched(document).getElementsByClassName('baz');
var links = watched(document).getElementsByTagName('a');

// need the length
var linkcount = links.length;

// access elements directly 
var aLink = links[0];

// or iterate
foos.forEach(function(element){
  console.log(element);
});

// finally, stay up to date, when elements are added
nodeList.on('added', function(addedElements){
    console.log(addedElements);
});

// removed
nodeList.on('removed', function(removedElements){
    console.log(removedElements);
});

// or changed in general
nodeList.on('changed', function(currentElements){
    console.log(currentElements);
});
