Facebook offers animated "emoji" responses to postings. Reactions do not correlate to particular emojis in the Unicode standard, but they are close: In response to COVID-19, Facebook added a "care" emoji reply as an extra choice in March 2020. Users can also add comments under posts to ask for more details or say thank you. Emojis can be used in conversations via text message or email. They can even be used in Facebook videos if someone adds a link back to something else on Facebook. Emojis are supported in most smartphones and tablets. People use emojis when they want to express themselves quickly and easily in text messages, emails, and even video chats. Even though emojis were designed to represent facial expressions, they can also be used to show other things like emotions, ideas, etc. There are many different types of emojis so you should be able to find one that fits your need. Users on social media have been using emojis since 2009 when they were first introduced on Twitter. Now people from all over the world use them every day to communicate about anything from the latest celebrity gossip to events going on around the world.
