WhatsApp, a subsidiary of Facebook, the world's largest social media company, has undergone several changes. In a recent news, we learned that WhatsApp will offer the option of Emoji Reactions in your chats. This option is available in their other social media like Facebook, Facebook Messenger, Instagram, and Snapchat.
This feature is not currently available for any version but soon you will see this version in your WhatsApp.
Using this feature you can instantly send your reactions via emoji without sending any separate emoji.
