Square-bracket array notation to get a DOM element from a collection, e.g. collection[3]. Since collections are extended JavaScript arrays, they behave similarly to standard arrays.

When an element method is used to create an element, the element will be wrapped in a collection. To access the DOM element within the collection, use collection[0]:

var circle =;
    el = circle[0];

alert(el.nodeName); // 'circle'

When a collection contains multiple elements:

var collection = Pablo(['g', 'circle', 'line']);
    el = collection[2];

alert(el.nodeName); // 'line'
