Explanation:

In Lightning Web Components, the decorators@api,@track, and@wireplay crucial roles. The@apidecorator is used to expose public properties and methods, making them accessible to other components. The@trackdecorator is used to mark private properties as reactive, so the UI updates when their values change. The@wiredecorator is used to wire Apex methods or Salesforce data to the component. Salesforce documentation on LWC development extensively covers these decorators, explaining their usage and best practices.

Explanation:

The format that the custom Salesforce relationship with the API name, My_Relationship_Name__r.My_Name__c is queried and transformed into by default in Salesforce B2B Commerce is myRelationshipName.myName: value. This is done to follow the JavaScript naming convention and to avoid conflicts with the standard Salesforce fields and relationships. The transformation rules are as follows:

Remove any namespace prefix from the field name, such as ccrz__ or cloudcraze__.

Remove any underscores from the field name and capitalize the first letter of each word after an underscore, such as MyRelationshipName and MyName. Lowercase the first letter of the field name, such as myRelationshipName and myName.

Use a dot (.) to separate the relationship name and the field name, such as myRelationshipName.myName.

Use a colon (:) to separate the field name and the field value, such as myRelationshipName.myName: value. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Query Transformation

Explanation:

Two data types that are considered discrete units of work (code units) within a transaction in the debug logs are web service invocation and Apex class. A discrete unit of work (code unit) is a segment of executable code that runs as part of a transaction in Salesforce. A transaction is a sequence of operations that are treated as a single unit of work and are executed under certain isolation and consistency rules. A transaction can consist of one or more discrete units of work (code units) that are executed sequentially or concurrently depending on various factors such as triggers, asynchronous calls, or limits. A debug log is arecord of database operations, system processes, and errors that occur when executing a transaction or running unit tests in Salesforce. A debug log can capture information about each discrete unit of work (code unit) within a transaction, such as its start time, end time, duration, events, variables, and limits. A web service invocation is a type of discrete unit of work (code unit) that involves calling an external web service from Apex code using SOAP or REST protocols. A web service invocation can be synchronous or asynchronous depending on the method used to make the callout. A web service invocation can be captured in a debug log with its details and results. An Apex class is another type of discrete unit of work (code unit) that involves executing Apex code that defines a class with properties and methods. An Apex class can be invoked from various sources such as triggers, Visualforce pages, Lightning components, or API calls. An Apex class can be captured in a debug log with its details and results.

A validation rule is not a type of discrete unit of work (code unit) within a transaction in the debug logs, as it is not a segment of executable code but rather a formula expression that defines a business rule for a field or object. A validation rule can be evaluated during a transaction and cause an error if the rule condition is not met, but it cannot be captured as a separate code unit in a debug log. A Lightning component load is not a type of discrete unit of work (code unit) within a transaction in the debug logs either, as it is not a segment of executable code but rather an event that occurs when a Lightning component is rendered on a web page or application. A Lightning component load can be measured by various performance tools such as Lightning Inspector or Lighthouse, but it cannot be captured as a separate code unit in a debug log.

Explanation:

The templating, JavaScript, and CSS frameworks that the cloudcraze managed package leverages are Bootstrap, Backbone.js, and Handlebars.js. Bootstrap is a CSS framework that provides responsive design and layout components. Backbone.js is a JavaScript framework that provides models, views, collections, and events for building single-page applications. Handlebars.js is a templating engine that allowsgenerating HTML from JSON data. Salesforce References: B2B Commerce and D2C Commerce Developer Guide, Front-End Development

Explanation:

The most likely cause of why some orders were missing from the Data Loader export is that the Status was still set to Draft. The Status is a field on the Order Summary object that indicates the current state of the order. The Status can have values such as Draft, Submitted, Confirmed, or Cancelled. A Draft order is an order that has not been submitted or confirmed by the customer or the seller. A Draft order is not considered a completed or valid order and is not included in reports or exports. When using Data Loader to export data from an org, Data Loader will only include orders that have a Status other than Draft, such as Submitted or Confirmed. If an order has a Status of Draft, Data Loader will not include it in the CSV file, which may result in missing orders. The export job did not fully complete is not a likely cause of why some orders were missing from the Data Loader
