Badges are symbols or emblems that represent achievements, skills, or affiliations. They are often used in various contexts, such as education, gaming, and professional settings, to recognize accomplishments or participation. Badges can be physical items, like pins or patches, or digital representations displayed on websites and profiles. In the digital world, badges are commonly used in online learning platforms and gaming environments. For example, platforms like Khan Academy and Duolingo award badges to users for completing tasks or reaching milestones. These badges serve as motivation and encourage users to engage more with the content or community.
