I like that Codecademy offers courses for a lot of programming languages, not just the popular ones. Codecademy provides quizzes and short exams after lessons to make sure that i understood the lesson. Also, i like that the videos of the courses have subtitles in different languages. I like the practical projects that Codecademy provides in order to test my knowledge.

Easy lesson track, practice, and theory section in the same page, you can apply all the knowledge you are acquiring during the lesson into the practice on the same page.

Codecademy is one of the best learn-to-code websites out there. I've used Datacamp, General Assembly, Coursera, LinkedIn Learning, Khan Academy, W3 school, Dataquest.io, and Udemy. Despite going through all that content, Codecademy does it the best because it's 1) intuitive and easy to use, 2) the curriculum allows the student to DO first before actually teaching the material. This could be done very poorly, but despite the user not knowing what the code does yet, it's still super easy to follow along and the explanations are spot on and informative. Can't speak highly enough of this resource- I recommend every single person to Codecademy before anything.
