Review Summary

Excellent work on this task! Your solution correctly implements all the requirements for creating, displaying, and hiding notifications. The code is functional and meets the primary objectives.

I have a couple of minor suggestions for future improvements:

1. When assigning classes, you can avoid duplication. Instead of container.className = 'notification notification ${type}', a cleaner way is to use container.className = notification ${type}
   ; or the more robust container.classList.add('notification', type);.
2. The if (container) check is not necessary. document.createElement will always return an element, or throw an error in rare cases like running out of memory, but it won't return a falsy value.

These are just best-practice tips and don't affect the functionality. Your submission is solid, and I'm approving it.

This check is not necessary. document.createElement will always return an element. In the rare case that it fails (e.g., out of memory), it will throw an error rather than returning a falsy value like null.

The class notification is being assigned twice here. While this works in the browser, it's redundant. You can simplify this to container.className = notification ${type};. An even more robust way to handle classes is using the classList property, like container.classList.add('notification', type);.
