function Slider(elementClass) { this.element = elementClass; this.printClass = function () { console.log(this.element); } } let slider = new Slider(".slider-elem"); slider.printClass();

read the page(s) from the link I gave to you: it will explain how 'this' works, in different context... what are you calling "a nested object"? A function constructor defined into another one? An instance initialized inside the outer constructor and of that "nested" constructor? or rather an instance initialized inside the outer constructor of another constructor outside? or... maybe provide a code to clarify your question ^^
