Review Summary

I am approving your solution because it correctly implements the pushNotification behavior as specified and meets all core functional requirements. Your function accepts the correct arguments, creates a div with the notification and type-specific class, adds an h2.title and p for the description, appends it to document.body, and hides the element visually after 2 seconds using setTimeout instead of removing it from the DOM. You also validate the notification type and coordinates and invoke the function three times for success, error, and warning, which satisfies the requirement to display all three message types.

One minor concern is that the function is not exposed globally (e.g., window.pushNotification), which some automated tests or external scripts might expect, but this is not a critical blocker for the task as described. Another non-blocking point is that hidden notifications accumulate in the DOM; in a real-world app you might later consider removing them after a longer delay or reusing elements, but this goes beyond the current requirements. Overall, your implementation is solid and aligned with the task, and these small potential improvements can be treated as optional learning opportunities for future projects.
