You can write better jQuery

While almost every new article mentioning it, talks about its demise, I’ve decided to write as about one of the most recurrent jQuery bad practices I came across and how to deal with it. Here it is:

Going from this:

$('.multiSelectOne').multiselect({
    buttonClass: 'btn btn-default',
    buttonWidth: '100%',
    ...
});
$('.multiSelectTwo').multiselect({
    buttonClass: 'btn btn-default',
    buttonWidth: '100%',
    nonSelectedText: '---',
    ...
});

To This:

<select class="js-multiselect" 
    data-include-select-all-option="true" 
    data-all-selected-text="All">
    <option></option>
</select>

$('.js-multi-select).each(function () {
    let options = {};

    Object.entries($(this).data())
        .map(property => options[property[0]] = property[1]);

  $(this).multiselect(options);

}

And never go back for adjustments in the script file ever again.
