[SOLVED] Can't access function

Help Requests
1

I have a JavaScript file that I want to use as a shared “utility”. It’s definition is as follows:

import $ from 'jquery';

export class SectionSwitcher {
    currentSection = null;

    constructor(id) {
        swap(id);
    }

    swap(id) {
        this.currentSection.hide("fast");
        this.currentSection = $("#" + id);
        this.currentSection.show("fast");
    }
}

and then I try to call the swap function in an instance of it in some other view model. For example:

this.sectionSwitcher.swap('some_element_id');

I get an error message as follows:

Error: Error invoking ViewModel. Check the inner error for details.

How does one make functions publicly available to other models?

Oops… never mind… the problem was in the constructor… when I used this.swap(id), then it’s fine.
