Testimonials

Vanilla JS makes everything an object, which is very convenient for OO JS applications.

Getting Started

The Vanilla JS team takes pride in the fact that it is the most lightweight framework available anywhere; using our production-quality deployment strategy, your users' browsers will have Vanilla JS loaded into memory before it even requests your site.

To use Vanilla JS, just put the following code anywhere in your application's HTML:

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

When you're ready to move your application to a production deployment, switch to the much faster method:

That's right - no code at all. Vanilla JS is so popular that browsers have been automatically loading it for over a decade.

Speed Comparison

Here are a few examples of just how fast Vanilla JS really is:

Retrieve DOM element by ID

Retrieve DOM elements by tag name

Code Examples

Here are some examples of common tasks in Vanilla JS and other frameworks:

Fade an element out and then remove it

Make an AJAX call

var r = new XMLHttpRequest(); 
r.open("POST", "path/to/api", true);
r.onreadystatechange = function () {
if (r.readyState != 4 || r.status != 200) return;
alert("Success: " + r.responseText); };
r.send("banana=yellow");

<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script> 

<script>

$.ajax({

    type: 'POST',

    url: "path/to/api",

    data: "banana=yellow",

    success: function (data) {

       alert("Success: " + data);

   }

});

</script>
