I had great fun and the workshops were really cool - you select an exercise, read the problem and start coding. Each exercise explains concepts and links to resources. Once you have written a solution to the problem, you invoke the workshop with your solution. Your solution is then ran and information regarding your success (or failure!) is printed to the terminal.
I'm a PHP developer by trade - the next day I thought to myself: is there something similar for PHP? There must be something similar for PHP? Turns out there wasn't!
