## Περιγραφή

Eliminate Render-blocking Javascript in above-the-fold content with Async Javascript.

Render-blocking Javascript prevents above-the-fold content on your page from being
rendered until the javascript has finished loading. This can impact on your page
speed and ultimately your ranking within search engines. It can also impact your
user’s experience.

Async JavaScript gives you full control of which scripts to add an ‘async’ or ‘defer’
attribute to or to exclude to help increase the performance of your WordPress website.

## Εγκατάσταση

Installation is very straightforward:

 1. Upload the zip-file and unzip it in the /wp-content/plugins/ directory
 2. Ενεργοποιήστε το πρόσθετο μέσω του μενού “Πρόσθετα” στο WordPress
 3. Go to `Settings` > `Async JavaScript` menu to load settings page

## Συχνές Ερωτήσεις

### Which browsers support the ‘async’ and ‘defer’ attributes

The ‘async’ attribute is new in HTML5. It is supported by the following browsers:

 * Chrome
 * IE 10 and higher
 * Firefox 3.6 and higher
 * Safari
 * Opera

### Where can I get help?

Async JavaScript is supported via [the wordpress.org support forum](https://wordpress.org/support/plugin/async-javascript).

### Do you offer professional support/ configuration services?

We offer premium services for Async JavaScript and full web performance optimization
services at [https://autoptimize.com/](https://autoptimize.com/?utm=asyncjs)

### What about CSS?

As the name implies, Async JavaScript is built to enhance JavaScript loading only.
Async JavaScript does not have any impact on CSS.

We recommend using the awesome [Autoptimize](https://wordpress.org/plugins/autoptimize/)
plugin alongside Async JavaScript for CSS optimization.

### I want out, how should I remove Async JavaScript?

 * Disable the plugin
 * Delete the plugin

I’ve been using this plugin for several months after it was suggested to me by a
colleague. The setup was simple, but also gives advanced options that I needed, 
such as excluding certain scripts. I had an issue recently, and the developer provided
fast and helpful support! I definitely recommend this plugin.

Exemplary support, and the plugin does exactly what it promises. This is unfortunately
not a given in a time when many other plugins try to cover more and more tasks and
end up in dangerous waters. Async JavaScript proves: Less is more.

This is the typical installation plugin you can’t miss in your project. Fulfill 
what you promise to do.

The plugin is easy to use. E.g with some videos on youtube. It improved our Google
Page Speed significantly. And when I had a support question I got feedback within
hours. Great Job. Keep up the good work

I love this plugin and I have been using it for a long time. It actually improved
my site stats on gtmetrix and pagespeed insights. However I recently added a forum
on my site using WpForo and found out that answer editor was failing to load. After
much research I discovered that this plugin is the one that was breaking the WpForo
answer editor so I decided to sacrifice it. I give 5 stars because, beside that 
tiny conflict, it works as advertised.
