Preliminary context: how does the Magento_Checkout/js/view/payment/default's placeOrder() work?

magento/magento2/blob/cf7df72/app/code/Magento/Checkout/view/frontend/web/js/action/place-order.js#L22-L40


if (!customer.isLoggedIn()) {
    serviceUrl = urlBuilder.createUrl('/guest-carts/:quoteId/payment-information', {
        quoteId: quote.getQuoteId()
    });
    payload = {
        cartId: quote.getQuoteId(),
        email: quote.guestEmail,
        paymentMethod: paymentData,
        billingAddress: quote.billingAddress()
    };
} else {
    serviceUrl = urlBuilder.createUrl('/carts/mine/payment-information', {});
    payload = {
        cartId: quote.getQuoteId(),
        paymentMethod: paymentData,
        billingAddress: quote.billingAddress()
    };
}
