Pros
Pro Welcoming, active community
freeCodeCamp strongly encourages interacting with other learners and experienced programmers. They provide chatrooms which are always active and full of members happy to answer any questions you may have. Pair programming (programming with another user) is encouraged as a great way to work through some of their coding challenges.
There are also meetup groups where you can code in person with other freeCodeCamp students.
Cons
Con Is an email list generator
Early focus isn't on programming. It is on signing up for all of FreeCodeCamp's social media and getting looped into their newsletters. The content is trivial. It is all just a massive marketing scheme to get email addresses of aspiring programmers to affiliate sell to by pushing novice developers to blog posts containing affiliate links.
That is until they sell to a 3rd party. Read their disclaimer. Whoever buys them out gets all their user data, email lists, etc.
Con Learning material is not in-depth
The teaching content provided by freeCodeCamp tends to act more as an introduction than a solid learning resource. Unless you already have some prior experience, you won't have enough knowledge to get through the coding challenges and development projects without using outside learning resources to fill in the gaps.
