Hi everyone. About a month ago I found out about this cool site thru a comment here on Hacker News. Even though I already have a level of programming expertise, I went thru some of the exercises provided here (for starters I chose the Javascript course) and I'm having fun resolving them and refreshing some basic concepts.
I believe this is a very useful site, specially for beginners.
Anyway, thank you for reading. I apologize for my English, I'm not a native speaker. Have a nice day!
