It’s simple. It works just how you think getElementsByClass would work, except better.

1. Supply a class name as a string.

2. (optional) Supply a node. This can be obtained by getElementById, or simply by just 
throwing in “document” (it will be document if don’t supply a node)). It’s mainly useful 
if you know your parent and you don’t want to loop through the entire D.O.M.

3. (optional) Limit your results by adding a tagName. Very useful when you’re toggling 
checkboxes and etcetera. You could just supply “input“. Or, if you’re like me, and you 
said Good Bye to IE5, you can use the “*” asterisk as a catch-all (meaning ‘any element).
