====== Configuration Setting: defer_js ======

**Note:** this is a feature flag. For now, you can change its setting, but the setting will be removed in the future and its default setting will become permanent behavior.

Usually, loading of JavaScript files (including big libraries like jQuery) pauses loading and assembling of other page resources (HTML/CSS/media/etc.). This slows down the initial page load, sometimes incredibly slows.

Since the "Hogfather" (2020-06-01) release, all JavaScript can be optionally used with a "defer" attribute for independent (asynchronous) loading its files and execution at the end of the assembly of all page resources. This speeds up the initial page load, sometimes incredibly speeds.

Until all plugins have been adjusted, the behavior may break the JavaScript of some plugins. If you encounter problems, you can disable the setting to revert to the old, slower behavior. Please also create a bug report to the respective plugin developer and refer them to [[devel:javascript]].
