Emojis have a come a long way since the days when we winked at each other with a semicolon, dash, and parenthesis. The website emojipedia.org reports that as of September 2021, there were more than 3,600 unique emojis in the Unicode Standard. They fall into eight categories, including Smileys and People, Animals and Nature, Food and Drink, Activity, Travel and Places, Objects, Symbols, and Flags.
