Cons
Con Lack of engagement in the forums
edX does not have the same forum participation from both students and instructors that other websites do, and the form of engagement often does not encourage discussion.
Con Courses aren't always available
While edX does offer some self-paced courses, you may end up waiting for the course of your choice to be run.
Con The forums are difficult to navigate
The forums are difficult to sort by date and topic, and are unintuitive to navigate.
Con Not production-ready
A few of the code examples are not ready for production, but they can easily be made into production-ready methods with some tweaks. The library has a stable release as of August 2018.
