The articles are good and very well explained what is going on. At the same time one gets to play with interesting math and puzzles. J is fun. Once in a while the author uses a function or operator that is unexplained, because one is expected to have some minimum knowledge of J (the J Primer or similar), but it is easy to look up in the vocabulary on the J homepage, so it is really easy to follow -- and fun, did I say that?
