Persisting the component state with reactive variables
In the previous chapter, we implemented some methods that allow us to like and comment on posts. However, there's one issue with this – after commenting or liking the post, the post element will be initialized and properties such as commentsShown will have an initial value of false, which will hide the comment box (and the comments' feed later) and display the latest comment.
This is not quite the intended behavior since we don't want the component to reset its internal state each time the user comments or likes a post. Instead, the user should be presented with the comment box and the comments' feed (which will be implemented later) until they choose to hide them.
The following screenshot shows a post once it's been liked and commented on:

This feature's implementation is a good candidate...
