What is if you accidentally like something on facebook then unlike it?

If you accidentally like something on Facebook, you can simply unlike it by clicking on the same button again. The like will be removed from the post and will not appear on your timeline or News Feed. However, if others have already seen the like or received a notification about it, they may still be aware of your initial action. It is also important to note that if the post is public, the person who posted it may still be able to see that you liked it even if you unlike it later.
