Using global effect properties

The effects module in jQuery includes a handy $.fx object that we can access when we want to change the characteristics of our animations across the board.

In the following examples, we'll take a look at a few of the documented properties.

To do so, we can simply set the $ property to true. For our demonstration, we will display a previously hidden button to allow the user to toggle animations on and off:

$(() => {...
