A great feature of jQuery when dealing with memory leaks was that it automatically cleaned data attributes and event listeners when nodes are removed or emptied.

Could you add this also to the empty and other dom node cleaning methods in this library?

It will be very useful to be able to do event delegation the jQuery way. This will greatly increase the speed of handling events - as you will handle them in a central place.

Maybe by passing a delegate: 'elem-selector' in the options of on() ?

it can be easily done with css selctor matches, like:

Use data attributes

.data(name, 1) => el.dataset.name

JQuery and Cash store the original display value and restore it again correctly.

Currently mQuery sets the display value to none/inherit, which can often be wrong, e.g. if the original display value was flex or hidden.

JQuery uses some sort of private cache: https://github.com/jquery/jquery/blob/a684e6ba836f7c553968d7d026ed7941e1a612d8/src/css/showHide.js

Cash uses some combination of storing the display value in a ___cd property on the element and calculating the display value based on inserting a temporary DOM element: https://github.com/fabiospampinato/cash/blob/1c1b316e53cc3322e417a93a0e7c4745852796d0/dist/cash.ts
