Calling prototype method from another object

Is it possible to call another prototype method inside a prototype method ? Like below.

jQuery(document).ready(function ($) {
    let gui = new GUI();
    let App = new App(gui);
});

var App = function(gui) {
    this.gui = gui;
    this.init();
    return this;
};

App.prototype.init = function() {
    this.gui.test();
};

var GUI = function() {
    return this;
};

GUI.prototype.test = function() {
    console.log("Test");
};
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

I would like to call something like this.

Best regards and thx for ur help

Yes, you certainly can. The only reason your code doesn't work is that you are shadowing App on the 3rd line.

Working code:

jQuery(document).ready(function ($) {
    let gui = new GUI();
    let app = new App(gui);
});

var App = function(gui) {
    this.gui = gui;
    this.init();
    return this;
};

App.prototype.init = function() {
    this.gui.test();
};

var GUI = function() {
    return this;
};

GUI.prototype.test = function() {
    console.log("Test");
};
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
