javascript - JS renaming methods -

i fed writing , reading getelementbyid , getelementsbytagname... makes programming harder me.

so want rename them. want them getid, gettags , getclasses.

it micro library after. how can result minimum cpu usage?

at least var doc = document; easy.

just assign them.

var doc = document;  doc.getid = doc.getelementbyid;  doc.gettags = doc.getelementsbytagname;  doc.getclasses = doc.getelementsbyclassname;  alert(doc.getid('foo').classname);

<div id="foo" class="classy"></div>

if want able leave out doc., you'll need define functions, e.g:

function getid(id) {     return document.getelementbyid(id); }
