What is can someone see if you like then unlike something on facebook?

If someone likes and then unlikes something on Facebook, it is possible that the person who posted the content may receive a notification informing them of the action. However, this notification may not show who liked and unliked the post. Additionally, if the post has a significant number of likes and dislikes, it may be challenging to identify the person who performed the action. It is important to note that Facebook policies allow users to change their interactions with content at any time, and all reactions to a particular post are anonymous by default.
