Question about Facebook notifications?

[Lost]

Will someone get a notification if I like something on their profile then unlike it even if we're not friends on facebook?

That person can get a like notification in their facebook, but not an ''unlike''.
If you put a like and then later an unlike, this person won't realize about the unlike. So don't worry

They'll get the notification that you liked it, but your like will be removed from the actual post.
