GUI extension - TabPage does not load JS

I am adding a new tab to the component editing screen. My tab displays fine, but JavaScript is not loading. I would like to write the URI of the current component in the tab. I feel that the names of my JavaScript methods are incorrect or consistent with the configuration, but I don’t really know how to say hello to JavaScript.

I used InfoTab View from CME Tridion (sample code below) as well as PowerTools ItemXml for inspiration - but no luck.

What is the minimum set of methods in JS for receiving greetings in the world?

Decision

Added node dependencies from the Rob clause. Then the log showed the js file as a download.

HelloTab.js

Type.registerNamespace("RC");

RC.HelloTab = function RC$HelloTab$HelloTab(element) {
    console.log('Constructor');
    Tridion.OO.enableInterface(this, "RC.HelloTab");
    this.addInterface("Tridion.Controls.DeckPage", [element]); //My extension is like this
};

RC.HelloTab.prototype.initialize = function HelloTab$initialize()
{
    console.log('init');
    $log.debug('init');
    this.callBase("Tridion.Controls.DeckPage", "initialize");
    $evt.addEventHandler($display.getItem(), "load", this.getDelegate(this.updateView));
};

RC.HelloTab.prototype.select = function HelloTab$select()
{
    console.log('select');
    this.callBase("Tridion.Controls.DeckPage", "select");
    this.updateView();
};

RC.HelloTab.prototype.updateView = function HelloTab$updateView()
{
    console.log('update');
    if (this.isSelected()) 
    {
        console.log('selected')           
    }
};

Tridion.Controls.Deck.registerPageType(RC.HelloTab, "RC.HelloTab");
