Thank you for your hard work on this project! While your code generally meets the task requirements, there are a few critical issues that need to be addressed before we can approve the pull request:

Error Handling: There are several instances where error handling is missing, particularly in the handleAddComment and handleDeleteComment functions. It's important to implement proper error handling to avoid silent failures and provide feedback to users.
Null Checks: Ensure that activePost is not null before accessing its properties to prevent potential runtime errors.
Form Validation: The logic for adding comments should include checks to ensure all fields are filled before proceeding. This will prevent incomplete submissions and improve user experience.
Accessibility: Consider using a button element instead of an a tag for actions that are not navigation-related to improve accessibility.
Code Cleanliness: Remove any commented-out import statements to avoid confusion and maintain clean code.

Please address these issues, and feel free to reach out if you have any questions or need further assistance. Keep up the great work! 🌟

+      setIsBodyEmpty(true);
+    }
+
+    if (postId !== undefined) {


The current logic only attempts to add a comment if postId is defined, but it does not check if all fields are filled before proceeding. Consider adding a check to ensure nameQuery, emailQuery, and bodyQuery are not empty before setting isLoading to true and calling handleAddComment.

+      ).finally(() => {
+        setBodyQuery('');
+        setIsLoading(false);
+      });


The finally block resets the bodyQuery and isLoading state, but it does not handle potential errors from handleAddComment. Consider adding a catch block to handle errors and provide feedback to the user if the comment submission fails.

-export const PostDetails: React.FC = () => {
  return (
    <div className="content" data-cy="PostDetails">


The data-cy attribute PostDetails is duplicated on this line and line 32. Consider removing one of them to avoid redundancy.

-          </p>
+          <p data-cy="PostBody">{activePost?.body}</p>


Ensure that activePost is not null before attempting to access its properties. Consider adding a conditional check to prevent potential runtime errors when activePost is null.

+            <a
+              href={`#user-${user.id}`}


The href attribute is used with a hash link, which is typically used for navigation. Since this link is used to trigger an action rather than navigation, consider using a button element instead of an a tag to better reflect its purpose and improve accessibility.

Great job on implementing the main functionality of your application! 🎉 While the code is generally well-structured and meets the task requirements, there are a few critical areas that need attention to enhance robustness and user experience:

Error Handling: The handleAddComment and handleDeleteComment functions lack proper error handling. It's important to provide user feedback and allow retry options when errors occur.
Null Checks: Ensure that activePost is not null before accessing its properties to prevent potential runtime errors. This is crucial for maintaining the stability of your application.
Form Validation: Improve the form validation logic in NewCommentForm.tsx by checking for empty fields and ensuring a valid email format before submission.
Accessibility: Replace a tags with button elements for non-navigation actions and use descriptive labels or aria-labels for buttons to improve accessibility.
Code Cleanliness: Remove commented-out import statements and address any eslint-disable comments to maintain clean and maintainable code.

These improvements will not only enhance the functionality and accessibility of your application but also provide a better user experience. Keep up the great work, and continue to learn and grow from these insights! 🚀

+                      onClick={() => handleDeleteComment(comment.id)}


Consider improving the accessibility of the delete button by using a more descriptive label or aria-label. This will help screen readers better understand the purpose of the button.

+            >
+              {user.name}
+            </a>


Consider using a button element instead of an a tag for non-navigation actions. This will improve accessibility and semantic correctness, as the current use of a tags for actions that do not navigate is not semantically correct.

+                handleActiveUser(user);
+              }}
+              onMouseUp={() => setIsActiveDropdown(false)}

+            </a>
+          ))}

      </div>


Ensure that the dropdown items are accessible by using appropriate roles and labels. Consider adding role="menuitem" to each dropdown item for better accessibility.
