The demo of the feature as shared by Chris Cox: <a href="https:&#x2F;&#x2F;www.facebook.com&#x2F;chris.cox&#x2F;videos&#x2F;10101920404101583&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.facebook.com&#x2F;chris.cox&#x2F;videos&#x2F;10101920404101583&#x2F;</a><p>Looking at it I was wondering what are the chances that it would lead to posting of an unintended reaction (&quot;Haha&quot; instead of &quot;Love&quot;). Once a reaction is tapped on, it is gone to the wild forever. There won&#x27;t be any undo.<p>With &#x27;Like&#x27; button there is no chance of accident as there is nothing else. And considering the reaction feature is being built for mobile - small screen, distracted attention, unsteady hands, the chances of &#x27;oops&#x27; scenario are quite high.
