Pro Courses are easy to understand
Pro Actual feedback on coding projects
You get actual feedback from developers on your code, which is useful. Yes having your sites/apps do what it is supposed to do is important, but you need feedback to learn industry standards/best practices and other gotchas that are much harder to learn on your own.
Con Lack of context
Codecademy is great for providing a hands-on approach, but there is a lack of context regarding how to start a project in real life. While users may learn how to code using Codecademy's interface, they may not have any idea how to code independently.
Codecademy is known to have many bugs which interfere with the editor, resulting in error messages despite having the correct answer.
Con Not the best structure for quick refreshers
The content of the lessons is aimed very much at people just starting to learn how to code. This is perfect for beginners but if you want to use Codecademy to refresh your knowledge the lessons are not designed to be quickly done.
Con Allows infinite loops to run
If you run an infinite loop, the browser freezes. Many other similar websites will give you an error, preventing the loop from running. Though not a bug, the lack of feature to stop infinite loops from running can be quite frustrating to beginners.
Con Deleted a lot of content
A lot of free content has been taken away, for example the PHP course was removed from the site.
Con Nanodegrees are expensive
Udacity is quite expensive at $200/month if you want to do a nanodegree.
