  Correct Answer:

  

  Box 1: F12 and select component

  Using browser developer tools to debug your code component

  Modern browsers have a built-in set of developer tools that allow you to inspect the HTML, CSS, and JavaScript loaded on the current page. You can access these developer tools using the keyboard shortcut Ctrl+Shift+I. Using the F12 key is

  also a common keyboard shortcut to open the developer tools.

  Box 2: Data Inputs

  Data Inputs is an interactive UI that displays all the properties and their types or type-groups defined in the manifest file. The contents of this area are dependent on the properties and datasets defined in the ControlManifest.Input.xml and

  allows providing mock data for test purposes.

  Box 3: Context Inputs

  Context Inputs is shown for all code component types:

  *

  Form Factor: Provides a way to specify the form factor and test the code component with each form factor (web, tablet, phone). This is helpful when the code component changes its layout depending on where the component is loaded. You can detect the form factor in the code using context.client.getFormFactor().

  Correct Answer:

  

  Box 1: IsOptimisticConcurrencyEnabled On a multi-threaded and multi-user system like Power Apps, operations and data changes often happen in parallel. A problem arises when two or more update or delete operations on the same piece of data happen at the same time. This situation could potentially result in data loss. The optimistic concurrency feature provides the ability for your applications to detect whether a table record has changed on the server in the time between when your application retrieved the record and when it tries to update or delete that record.

  Box 2: If-Match: Etag Use If-Match and If-None-Match headers with ETag values to check whether the current version of a resource matches the one last retrieved, matches any previous version or matches no version. These comparisons form the basis of conditional operation support. Dataverse provides ETags to support conditional retrievals, optimistic concurrency, and limited upsert operations.
