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/view/payment/default.js#L137-L157


if (this.validate() && additionalValidators.validate()) {
    this.isPlaceOrderActionAllowed(false);


    this.getPlaceOrderDeferredObject()
        .fail(
            function () {
                self.isPlaceOrderActionAllowed(true);
            }
        ).done(
            function () {
                self.afterPlaceOrder();


                if (self.redirectAfterPlaceOrder) {
                    redirectOnSuccessAction.execute();
                }
            }
        );


    return true;
