@RALifeCoach as far as I understand in 3.0 .attr no longer exists, instead there are automatically populated getters and setters, so where you would have said
let foo = this.attr('bar');
you would now say
let foo = this.bar;
and to set the value of the attribute you'd say
this.bar = someValue;
unless you are trying to get an attribute from the DOM element which would be $(this.element).attr I believe(don't quote me on that part)
