Format price with javascript in Magento 2

Take a look at shipping_method/price.js

define(
    [
        'jquery',
        'Magento_Checkout/js/model/quote',
        'Magento_Catalog/js/price-utils'
    ],
    function ($,quote, priceUtils) {
        "use strict";
            ......
            formatedPrice = getFormattedPrice(price)

            getFormattedPrice: function (price) {
                //todo add format data
                return priceUtils.formatPrice(price, quote.getPriceFormat());
            }
        });
    }
);

Based on the answer of R.S

define([
    'jquery',
    'Magento_Catalog/js/price-utils'
], function ($, priceUtils) {
    "use strict";

    function irreleventCalculations() {
        // black magic here
        return 19.949999;
    }
    var price = irrelevenCalculation();
    price = priceUtils.formatPrice(price);


    jQuery('#myCustomPriceDiv').text(formatedPrice);

    return $;
});
