Codecademy
Toca una estrella para valorar
Codecademy teaches programming through interactive lessons where you write code directly in your browser and get instant feedback. The free tier gives you access to a solid collection of lessons across Python, JavaScript, HTML, and other languages. If you want to build full projects or earn a professional certificate, the Pro subscription adds those features at a reasonable monthly cost.
The hands-on approach helps many people learn faster than video lectures alone. Beginners especially benefit from writing code immediately rather than just watching, making it a straightforward path into web development or data science basics.
