This mission is to build reactions began just over 5 years ago in 2015. Mark Zuckerberg had finally conceded that not every post is likable.and after 2015 Facebook allowing users to respond to post with some emojis as opposed to just a thumbs up.
Facebook is in the action of creating a developing a new reaction button based on COVID-19. this discovered by well-known app researcher Jane Manchun Wong. He said, “Facebook is working on a COVID-19 themed reaction” when shared on twitter.
This button simulates a heart, is similar to an icon already used on Facebook for its new “COVID-19 information Center Feature”.it remains uncertain what exactly this button purpose will be and it’s also strange when the button will be available to Facebook users.
