Coding platforms are online environments where users can write, test, and share code. They often provide tools and resources for various programming languages, making it easier for beginners and experienced developers to collaborate and learn. Popular examples include GitHub, Replit, and CodePen. These platforms typically feature integrated development environments (IDEs) that streamline the coding process. Users can access tutorials, documentation, and community support, enhancing their coding skills. Many coding platforms also host coding challenges and competitions, encouraging users to improve their abilities while engaging with others in the programming community.
