Ask HN: Is self-learning front end development through freeCodeCamp reliable?

I'm a beginner in frontend development, currently only familiar with basic HTML and JavaScript. I'm looking to learn React next and considering using freeCodeCamp (https://github.com/freeCodeCamp/freeCodeCamp) as my learning resource.

Has anyone here used freeCodeCamp for learning frontend, especially React? How was your experience? Is it effective for self-learners?

I'd appreciate any insights on: 1. The quality and depth of their React curriculum 2. How well it prepares you for real-world development 3. Any alternatives you'd recommend for a beginner

Thanks in advance for your advice!
