Last February, Facebook finally let users do more than “Like” a post. The introduction of emoji reactions let everyone love, laugh, shed tears, feel angry, and act surprised (or, as Facebook put it, “wow”) in response to a shared status or link.
You react to a comment in the same way you react to a regular post. Simply press and hold down the Like button on the app to select your reaction. On desktop, hover over the thumbs-up to see your options.
On desktop, multiple reactions to comments look a bit too crammed into one space. On mobile, they’re more spaced out, and it’s easier to see who’s loving, liking, and wow-ing a comment.
Go cry, laugh, or scream if you must. As of today, for better or worse, there's no limit to showing how you really feel on Facebook.
