• A (selector) to "query (or find)" HTML elements

• An action() to be performed on the element(s)

Examples:

$("p").hide() - hides a <p> element.

$(".test").hide() - hides an element with class="test".

$("#test").hide() - hides the element with id="test".

$niper('#button').remove(); - removes the button

or pass a second arguement to the selector with true

$(".button",true) — Selects all the elements with class of .button NOTE: Without an asterisk * in front, it will always return only one element
