  • Amazing course to learn React basics from scratch. All you need to know beforehand is the latest JavaScript syntax. Interactive examples and live preview of your code is what makes this course unique and easy to grasp.

  • I was struggling to find a proper React course — glad I found Codecademy. Love how they teach you every bit of what React has to offer to date. Now I have the confidence to create my own React apps :)

  • This course teaches you React from the very basics up to a really good level of understanding of the framework like no other. It's complicated to find a proper way of learning React. Video courses are fine, but there's nothing like 'getting your hands dirty' while having an interactive environment and a text guide. It makes you feel smart because you understand the topic! I loved it and I've already recommended Codecademy and their courses to people.
