Explanation:

The correct syntax to render a property in a Lightning web component template is to surround the property with curly braces: {property}. This syntax allows you to access the property value from the JavaScript class of the component and display it in the HTML template. The other options are incorrect because they either use invalid characters or do not follow the standard syntax for rendering a property in a Lightning web component template.

The method that needs to be implemented when rendering a Salesforce B2B Commerce view in order to have it called after rendering has finished is postRender. This method is an optional hook that can be defined by the user to perform any actions or logic that depend on the view being rendered, such as initializing widgets, binding events, or updating the user interface. The method will be called by the render method of the CCRZ.View class, which is the base class for all views in the framework.

Explanation:

To make an API call in a Lightning web component (LWC), a developer should use the connectedCallback lifecycle hook. The connectedCallback lifecycle hook is invoked when the component is inserted into the DOM. This is the ideal time to make an API call, as the component is ready to receive and display data. Thedeveloper can use the fetch API or a third-party library, such as axios, to make the API call and handle the response. The renderedCallback lifecycle hook is not a good choice for making an API call, as it is invoked every time the component is rendered or rerendered. This can cause unnecessary or repeated API calls and affect performance. The errorCallback lifecycle hook is not a good choice either, as it is invoked when an error occurs in the component or in one of its children. This is not related to making an API call, but rather to handling errors. The disconnectedCallback lifecycle hook is not a good choice either, as it is invoked when the component is removed from the DOM. This is not a suitable time to make an API call, as the component is no longer visible or active.

Three attributes that are true regarding Subscriber Pages are: Subscriber Pages can include additional standard Salesforce B2B Commerce components such as featured products, category tree, and mini cart. These components can be added to the Subscriber Pages by using the CCRZ.pagevars.pageLabels and CCRZ.pagevars.pageSections objects, which contain the page labels and page sections that are defined in CCAdmin. Subscriber Pages allow customers to quickly create new custom pages for their storefront. These pages can be used to display any content or functionality that is not available in the default pages, such as FAQs, testimonials, or promotions. Out of the Box, Subscriber Pages are completely blank HTML pages. These pages do not have any predefined layout or content, so the user can customize them according to their requirements. The user can use Visualforce, HTML, CSS, JavaScript, or any other web technologies to create their own Subscriber Pages.

Explanation:

To make Lightning Web Components mobile-ready, one maintainable approach is to create a Lightning app page and then add the component to the mobile navigation. This ensures that the component is accessible and optimized for mobile users within the Salesforce mobile app. Another approach is to design the component's templates with responsiveness in mind, using CSS and layout techniques that adapt to different screen sizes. Salesforce documentation on mobile-ready development practices provides guidelines on creating responsive designs and optimizing components for mobile use.
