To debug a flow and watch all the variables changing as the checkout process is executed, the developer needs to enable two features: show the details of what is executed and render flow in Lightning Experience, and show the details of what is executed and render flow in Lightning Runtime. These features are available in the Debug Options dialog box in Flow Builder, and they allow the developer to see the detailed information about each element, resource, and variable in the flow as it runs.The developer can also use breakpoints to pause the flow execution and inspect the variable values at any point1.Running the latest version of each flow called by subflow elements is not a feature that affects the display of variables, but rather a feature that ensures that the debug session uses the most recent version of any subflows2.Setting up a debug log is not a feature that can be enabled in Flow Builder, but rather a separate tool that can be used to monitor the events that occur when a flow runs3.Reference:Debug a Flow in Flow Builder,Flow Debugging,Debug Flows with Debug Logs

To see the changes made to the products of an existing storefront, the developer needs to publish the catalog that contains those products. Publishing a catalog makes the catalog data available to the storefront and updates the search index with the latest product information. Publishing a catalog also activates any product lists that are associated with the catalog. Therefore, activating the product list or rebuilding the search index are not necessary steps. Publishing the storefront is also not required, as it only affects the layout and appearance of the store, not the product data.Reference:Publish a Catalog,Manage Catalogs

To translate the text values in a custom Lightning web component (LWC) for the storefront, the developer should create custom labels for the text values and import them in the LWC. Custom labels are text values that can be translated into any language that Salesforce supports. The developer can create custom labels in Setup and assign them to a category for easier management. The developer can also use the Translation Workbench to provide translations for the custom labels in different languages.To use the custom labels in the LWC, the developer must import them from the @salesforce/label scoped module and use them in the HTML template or the JavaScript file1. This approach allows the developer to reuse the custom labels across multiple components and leverage the built-in translation features of Salesforce.

Importing static resources or using a CustomLabel xml file are not valid ways to translate the text values in a LWC, as they do not support dynamic language switching or translation workbench integration. Creating a custom metadata object for the text values and querying it in the LWC is possible, but it is more complex and less efficient than using custom labels.Reference:Use Custom Labels in Lightning Web Components

To compare a CSS file containing small changes with the version deployed to the org, the developer can right-click the CSS file and choose Diff File Against Org. This will open a diff view in Visual Studio Code that shows the differences between the local file and the org file. The developer can use this feature to verify if the changes were deployed or not.This feature requires the Salesforce Extension Pack and the @salesforce/sfdx-diff plugin to be installed in Visual Studio Code12.Reference:SFDX: diff file against org #1584,Salesforce Diff - Visual Studio Marketplace

To authorize an org and begin deploying Lightning web components, the developer can use either of these two sets of steps:

Run the command: 'sfdx force:auth:web:login -r ''https://login.salesforce.com'' and then supply the credentials in the browser when it opens. This command opens a browser window and prompts the developer to log in to the org. The -r flag specifies the login URL for the org, which can be changed to https://test.salesforce.com for a sandbox or scratch org.The developer can also use the -a flag to set an alias for the org, which makes it easier to identify and reference later1.

Open Visual Studio Code, Create a project using ''SFDX: Create a Project'' and then ''SFDX: Authorize an Org'' from the Command Palette. This option allows the developer to use the Visual Studio Code interface to create a new project and authorize an org. The developer can access the Command Palette by pressing Ctrl+Shift+P (Windows) or Cmd+Shift+P (Mac), and then typing or selecting the commands. The developer can choose the project template, name, and folder location, and then select the login URL for the org.A browser window will open and prompt the developer to log in to the org2.

The other options are not valid ways to authorize an org and begin deploying Lightning web components. Running the command 'sfdx force:auth:web:login -a ''https://login.salesforce.com'' will result in an error, as the -a flag is used for setting an alias, not a login URL. Creating a project and authorizing an org using the command ''SFDX: Create Project and Authorize'' in the Command Palette is not possible, as there is no such command available in Visual Studio Code.Reference:Authorize an Org Using a Browser,Create a Project

To expose a public property in a Lightning web component, the developer should decorate the field with @api. The @api decorator marks a public reactive property that can be set by another component that uses this component.The property value is passed from the owner component to the child component3. For example, if a parent component has a property called message, it can pass its value to a child component by using an attribute with the same name in the HTML template:

<c-child message={message}></c-child>

The child component can access this value by declaring a public property with @api:

import { LightningElement, api } from 'lwc'; export default class Child extends LightningElement { @api message; }

The other decorators are not used to expose public properties in a Lightning web component.The @property decorator is used to define private reactive properties that are internal to the component4.The @track decorator is used to mark private fields as reactive, so that changes to their values trigger a re-render of the component5. The @public decorator does not exist in Lightning web components.Reference:Public Properties,Private Properties,Reactive Properties

The equivalent of the code in a Lightning Web Component is Option A. This is because the <template> tag is used in a Lightning Web Component to define the HTML structure of the component. The <c-child> tag is used to include a child component in the parent component. The <c-child first-name=''{fName}''> tag is used to pass data from the parent component to the child component using a public property called firstName. The @api decorator in the child component indicates that the firstName property is public and can be set by the parent component. The {firstName} expression in the child component template renders the value of the firstName property.Reference:Communicate with Events,Pass Data to Child Components

To make a Lightning web component available in the Lightning Page Builder, the developer needs to ensure that the metadata isExposed property is set properly in source code and that it has a target of lightning__FlowScreen. The isExposed property in the component configuration file (the .js-meta.xml file) determines whether the component is exposed to Lightning App Builder or not.The developer must set this property to true to make the component visible in the builder1. The target property in the same file specifies where the component can be used.The developer must include lightning__FlowScreen as one of the targets to make the component available for flow screens2. Redeploying the component or closing and reopening the browser will not solve the issue if the metadata properties are not configured correctly.Reference:Expose Your Component to Lightning App Builder,Configure Components for Flow Screens
