• How to know the Checkout Method Status of the user is Guest or Registered Magento 2?

While working on the checkout page, You can know the current customer is a Guest or registered customer using checking the customer login status.

Create a customer object and it contains many functions to customer-related functionality.

Create a JS file in your module or theme level,

define([
    'Magento_Customer/js/model/customer',
], function (customer) {
        'use strict';

        return {
            /**
             * @return {String}
             */
            getCheckoutMethod: function () {
                return customer.isLoggedIn() ? 'customer' : 'guest';
            }
        };
    }
);

Now you need to call this.getCheckoutMethod() method to know the status of the customer.
