    Codecademy

    Codecademy is a well-known interactive platform that teaches coding and computer science fundamentals through hands-on practice. Launched in 2011, Codecademy’s mission is to democratize tech education by making it accessible and engaging for everyone. The platform offers free and paid plans covering programming languages like Python, JavaScript, HTML/CSS, SQL, and more. Codecademy Pro includes guided learning paths, quizzes, portfolio-building projects, and real-world exercises. One of the platform’s most compelling features is its built-in code editor, allowing users to practice coding immediately after learning a concept—ideal for learners who retain knowledge through doing rather than watching. Codecademy’s career tracks guide users toward jobs like front-end developer, back-end developer, or data analyst. While it doesn’t issue formal degrees or certificates recognized by universities, its completion certificates and practical exercises are highly valued in entry-level tech hiring. The clean interface, gamified experience, and flexible pace make Codecademy particularly appealing for beginners, self-learners, and hobbyists starting their programming journey.
