As a fellow beginner (learning for well over a year, on and off), I'll show a way I would do it:
isAnagramOf =: -:&:(-.&' '@:/:~@:tolower) I think Henry mentioned using the above conjunctions. Also, as Henry said, Dissecting the verb is a great way to see what happened. NB. name the string literals, it makes life easier lhs =: 'a b C' rhs =: 'cB a' space =: ' ' load 'debug/dissect' dissect 'lhs ( -:&:(-.&space@:/:~@:tolower)) rhs' On top of JForC and Roger Stokes' book, and of course the Dictionary and Nuvoc, I found the "Brief J Reference" really helpful: http://www.jsoftware.com/books/pdf/brief.pdf Especially pages 17 and 18, which give a great overview (in diagram form) of J's conjunctions, forks and hooks, without discussing rank, which of course is important, but, for me at least, these diagrams really made the whole concept click.

So far I've spent some evenings reading and experimenting with the language. J is fun. Real fun. I also like how J forces me to re-consider how I view programming. Of course, that also means I'm still at a complete beginner's stage, so I'd like to ask for some feedback and suggestions on my first J code. I'm sure there's a lot I can simplify in my code. Here's the code I put together by digging around in the J Dictionary: isAnagramOf=:(0:`((*/)@(=&((/:~@tolower)@(' ' & i.#])))))@.(=&(#@:(' ' & i.#]))) Some examples: 'Nag a Ram ' isAnagramOf 'Anagram'1 'ab' isAnagramOf 'aa'0 All tips and hints on both the code and learning J in general would be much welcome.
