Vanilla jQuery

vanilla.js

/*
This is a small class for replicating the most often-used (by me, at least) jQuery functionality in 2kb. Tested in newest browsers and IE8. Examples follow.
Includes:
  * Find elements
  * Create element
  * Update attributes for element
  * Iterate through elements with callback
  * Bind events with callback
  * Empty children from element
  * Load script
  * Get and set element text
  * Doc Ready

Other useful shortcuts built into js:
parent = element.parentNode
clone = element.cloneNode(true)
next = element.nextSibling
html = element.innerHTML
addClass = element.classList.add("foo")
removeClass = element.classList.remove("foo")
toggleClass = element.classList.toggle("foo")
