This utility library originated from quirks in iOS which normalises unwanted some jQuery event duplicates.

The utility's main object can be directly accessed via the ƒ character (alt+159 or alt+0131 on windows) (⌥ Opt + f on mac) can also be referred to as fixx

var ƒ = ƒ || {}, fixx = ƒ;

ƒ cannot be chained like jQuery as it's a utility library, not a DOM manipulation library.

Object references are passed to most of the ƒ methods which means there are no prerequisites for adding special classes or identifiers to DOM elements for it to work.

to get the current version, call ƒ.version
Returns a string value of the current library version

Make sure the file itself is saved with UTF-8 encoding and you can also add the charset attribute in the script tag when including the script on the page.

<script src="fixx.min.js" charset="UTF-8"></script>

Saving with encoding in Visual Studio:

File → save as → bottom right button arrow: "save with encoding" → UTF-8

Setting encoding in Notepad++:

Open file in Notepad++
Main menu option "encoding"
select "Save in UTF-8 without BOM"
Save the file
