Answer 1

Usually class refers to the class attribute of any object like <div >, <input > etc. which shows displays class as <div class="someclass">

Answer 2

class is reserved words in javascript

Answer 3

Yep, class is a reserved word. MDN

Answer 4

You need to add quotes round the class which is a reserved word. Please also note, that you should remove the last comma:

var defaults = {
        id: 'ActionSlider',
        element: '',
        closeBtnWidth: 55,
        panelWidth: 320,
        "class": '',
        css: {},
        create: function() {}
    }
