Overview

Vanilla JS is a fast, lightweight, cross-platform tool for building incredible, powerful JavaScript applications.

Use in Development

Just put the following code:

<!-- <script src="path/to/vanilla.js"></script> -->

Use in Production

The much faster method:

Summary

Speed Comparison

When Vanilla JS perform 100 operations, others do:

Retrieve DOM element by ID

	Code	100 ops Vanilla JS
Vanilla JS	document.getElementById("vanilla");	100
Dojo	dojo.byId("dojo");	92
Prototype JS	$("prototype");	57
jQuery	$("#jquery");	42
MooTools	document.id("mootools");	24

Retrieve 10 DOM elements by tag name

	Code	100 ops Vanilla JS
Vanilla JS	document.getElementsByTagName("div");	100
Prototype JS	Prototype.Selector.select("div", document);	25
jQuery	$("div");	21
jQuery	dojo.query("div");	3
MooTools	Slick.search(document, "div", new Elements);	2

Vanilla JS vs jQuery

Retrieve 10 DOM elements by class name

	Code	100 ops Vanilla JS
Vanilla JS	document.getElementsByClassName("vanilla");	100
jQuery	$(".jquery");	25

Retrieve DOM element with `<#id> .inner span` selector

	Code	100 ops Vanilla JS
Vanilla JS	document.querySelector("#vanilla .inner span");	100
jQuery	$("#jquery .inner span");	17

Retrieve 10 DOM elements with `<.className> .inner span` selector

	Code	100 ops Vanilla JS
Vanilla JS	document.querySelectorAll(".vanilla .inner span");	100
jQuery	$(".jquery .inner span");	51

Vanilla JS Selector Performances

All tests are based on <section id="vanilla" class="vanilla"><article class="inner"><div class="target" id="target"></div></article></section> HTML.

Select node `<div class="target" id="target"></div>`	100 ops Vanilla JS
document.getElementsByTagName("div");	100
document.getElementById("target");	99
document.getElementsByClassName("target");	96
document.querySelector(".vanilla .inner div");	68
document.querySelectorAll(".vanilla .inner div");	35

From jQuery to Vanilla JS

Legend

Understand each type of DOM Object:

<div class="example">
  <span>(Text into) Html Element</span>
  <!-- Comment Element -->
  Text Element
  <span>(Text into) Html Element</span>
</div>

querySelector(".example") return a HTMLElement.
querySelector(".example").children return a HTMLCollection, each collection's item is a HTMLElement, two [span, span] here.
querySelector(".example").childNodes return a NodeList, each collection's item is a Node, seven [text, span, text, comment, text, span, text] here.
querySelector(".example").childNodes[0] return a Text (Node) of typeNode 3, as a text. (...nodeList[3] is typeNode 8 as a Comment (Node too)).
