The best feature about Codeacademy is that the entry-level courses are free. I frequently refer people to this site who think they might be interested in coding. The site does a great job of explaining things thoroughly. Most importantly, the courses include lots of required interaction and participation.

the courses offered are great for a complete beginners who would like to get some into to the subject.

I love the fact that it's interactive. It starts with the basics and guides you through and tests you along the way. I am really enjoying it.
