The handlebars helper function that is used on Salesforce B2B Commerce pages and components for formatting price values is formatPrice. Thisfunction will format a numeric value as a price according to the currency settings and locale of the storefront. For example, {{formatPrice price}} will format the price value as $1,234.56 for US dollars or €1.234,56 for euros.

A cart item with a type of Charge is created with the Cart Delivery Group Method after the shipping integration. A shipping integration is an integration that calculates and applies shipping costs and options to a cart or an order basedon various factors, such as product weight, dimensions, quantity, location, andcarrier service level. A shipping integration can use either an external shipping service provider or custom Apex code to perform the shipping calculation. The Cart Delivery Group Method is a method that determines how products are grouped into delivery groups based on their shipping methods and addresses. A delivery group is a logical grouping of products that are shipped together using the same shipping method and address. After performing the shipping calculation for each delivery group, the shipping integration creates a cart item with a type of Charge and a charge type of Shipping for each delivery group. These cart items represent the shipping costs and options that are applied to each delivery group. A cart item with a type of Surcharge, Shipping, orDelivery does not exist or is not related to the shipping integration.

Thetemplate that will correctly display the details message only when areDetailsVisible becomes true given the following code in a Lightning Web Component is option C. Option C uses the if:true directive to conditionally render a template block based on the value of areDetailsVisible. If areDetailsVisible is true, the template block inside the <template if:true={areDetailsVisible}> tag will be rendered. Otherwise, it will be skipped. Option A is incorrect because it uses the if:false directive, which does theopposite of if:true. It renders the template block only when areDetailsVisible is false. Option B is incorrect because it uses an invalid syntax for the if directive. The if directive requires a colon (:) after the if keyword, not an equal sign (=). OptionD is incorrect because it uses an invalid syntax for the template tag. The template tag requires a closing tag (</template>), not a self-closing tag (<template/>).

When a developer configures a tax integration for a store, the previously calculated tax entries during the checkout flow are deleted from the Cart. A tax integration is an integration that calculates and applies tax rates and amounts to a Cart or an Order based on various factors, such as product type, price, quantity, location, and tax rules. A tax integration can use either an external tax service provider or custom Apex code to perform the tax calculation. When a developer configures a tax integration for a store, any existing tax entries in the Cart are deleted before calling the tax integration service or method. This ensures that the tax calculation is accurate and up-to-date based on the current state of the Cart and avoids any conflicts or inconsistencies with previous tax entries. The previously calculated tax entriesare not ignored during recalculation, saved prior to recalculation, or modified with the new tax calculation, as these are not valid actions for handling existing tax entries.

 The correct way to demonstrate the passing of a message from the grandchild component to the grandparentcomponent in LWC is to use the PubSub library. The PubSub library is a utility that enables Lightning web components to communicate across the DOM tree without using intermediaries. The grandchild component can publish a message to a channel, and the grandparent component can subscribe to that channel and receive the message. This way, the communication is decoupled and does not depend on the component hierarchy. Option B shows the correct syntax for using the PubSub library to pass a message from the grandchild component to the grandparent component. Option A is incorrect because it uses the @api decorator to expose a property on the grandchild component, which is not a valid way to communicate with the grandparent component. Option C is incorrect becauseit uses the @wire decorator to wire a property on the grandchild component to a function on the grandparent component, which is also not a valid way to communicate with the grandparent component. Option D is incorrect because it uses the @track decorator to track a property on the grandchild component, which is not a valid way to communicate with the grandparent component. References: Communicate Across the DOM |Lightning Web Components Developer Guide, Child to grandparent communication in LWC, PubSub Library for Lightning Web Components

In Lightning Web Components, wire adapters are used to retrieve and manipulate Salesforce data. Wire adapters abstract the underlying data access mechanism, providing a declarative way to access Salesforce data and metadata. Salesforce documentation on LWC andthe@wiredecorator details how wire adapters can be used to connect components to Salesforce data sources, including standard and custom objects, facilitating reactive data binding and efficient data retrieval.

If a developer leaves debug mode turned on in an environment, the user will begin getting JavaScript limit exceptions.Debug mode is a setting that enables more detailed logging and error reporting for Lightning web components. However, it also increases the size and complexity of the JavaScript code that is delivered to the browser, which can cause performance issues andJavaScript limit exceptions. The JavaScript limit exceptions are errors that occur when the browser reaches its maximum capacity for executing JavaScript code, such as memory heap size or script execution time. The performance of the org will not become slower each day, as debug mode only affects the client-side performance, not the server-side performance. The org will not turn off debug mode after 72 hours, as debug mode is a persistent setting that can only be changed manually by an administrator. A banner will not be displayed to the user indicating that the org is in debug mode, as debug mode is a transparent setting that does not affect the user interface.

Data for Lightning web components should be provided as independent properties that take simpler, primitive values (e.g. String, Number, Boolean,Array). Providing data as independent properties allows the developer to expose data as public or private properties of the Lightning web component and communicate data between components or services. Providing data as simpler, primitive values allows thedeveloper to use data types that are supported by JavaScript and Lightning web components and avoid unnecessary or complex conversions or transformations. Providing data as a few properties that contain sets (objects) of data is not a good way to provide data for Lightning web components, as it can create confusion or inconsistency in data structure and access. Providing data as one property that contains all data in one set (object) is not a good way either, as it can create complexity or inefficiency in data management and manipulation. Providing data as a single property object that contains sets (objects) of data is not a good way either, as it can create redundancy or duplication in data storage and retrieval.

The conversion flag that allows for sObjectsto be returned from the Global API’s when provided as a Boolean parameter with a value of true is ccrz.ccAPI.SZ_SOBJECT. This flag indicates that the API should return the raw sObjects instead of the transformed objects that are usually returned by the API. For example, ccrz.ccServiceProduct.getProducts(ccrz.ccAPI.SZ_SOBJECT,true) will return the Product2 sObjects instead of the ccrz__E_Product__c objects.

After deploying a new Lightning Web Component (LWC) to an org, the typical next step to use the component on a page involves navigating to that page, entering the edit mode (usually through AppBuilder or a similar interface), and then dragging the new component fromthe components palette onto the desired location on the page. This process is consistent with Salesforce's modular design approach, allowing for easy integration and configuration of components within the Salesforce ecosystem.
