Well over a month after it brought the reaction feature to Mobile messenger apps , the latest Facebook updates now allows anyone react to just about anything , except the ability react to reactions themselves.

The latest update functions same way you react to a News Feed post: just hover over the Like button in a comment if you are on desktop app or tap & hold the Like icon until you see the reaction emoji if you are on mobile .

The feature is rolling out in phases to Mobile & desktop users , so you need not worry if you are yet to see this on you device.
