### Removal of old JavaScript

This fork uses downsized/simplified versions of scripts and has no support for Internet Explorer.

The result is faster and smaller download code (good for mobile networks).

Things might work in Edge 18, Firefox 50-62 and Chrome 54-68 due to one polyfill for array.flat().

* Added dev/prototype-*.js for some additional features
* boot.js without webpack overhead
* Replaced jQuery with jQuery.slim
* Replaced ProgressJS with simple native dropin
* Replaced Autolinker with simple https/email detection
* Replaced ifvisible.js with simple drop-in replacement
* Replaced momentToNode with proper HTML5 <time>
* Replaced resize listeners with ResizeObserver
* Replaced bootstrap.js with native drop-in replacement
* Replaced dev/Common/ClientStorageDriver/* with Web Storage Objects polyfill
* Removed pikaday
* Removed underscore
* Removed polyfills
* Removed Modernizr
* Removed nanoscroll
* Removed jquery-scrollstop
* Removed jquery-mousewheel
* Removed matchmedia-polyfill
* Removed momentjs (localization still used)
* Removed opentip (use CSS)
* Removed non-community (aka Prem/Premium/License) code
* Modified Jua.js to be without jQuery

649.415 bytes (199.090 gzip) is not much, but it feels faster.

### Squire vs CKEditor
The [Squire](https://github.com/neilj/Squire) implementation is not 100% compatible yet, but is shows the massive overhead of CKEditor.

Still TODO:

* support for tables (really needed?!?)
* support BIDI (really needed?!?)

|       	| normal	| min    	| gzip  	| min gzip	|

|squire  	| 128.826	|  47.074	| 33.671	|   15.596	|
|ckeditor	|       ?	| 520.035	|      ?	|  155.916	|

CKEditor including the 7 asset requests (css,language,plugins,icons) is 633.46 KB / 180.47 KB (gzip).

Enable it in /data/\_data\_/\_default\_/configs/application.ini in the [labs] section add/edit: `use_squire_html_editor = On`

### PHP73 branch

There's a branch with only the PHP 7.3 changes at
