The proposed Javascript is more along the lines of: execute a function (do_something) on the value of each (for (var prop)) of the variabiles contained in a specified locale (a). So, a literal translation would involve the retrieval of the list of the variable names (b and c in the exampple, but it could be anything, including an empty list) defined in the locale "a", the extraction of their values. In a relatively recent version of Dyalog APL (sorry I can't do it in J) you could write:
a<-[]NS '' a.b<-'bee' a.c<-'see' do_something each a.(execute each []nl -2) where "<-" stands for the left-arrow assignement, "[]" for the "quad" symbol, "each" and "execute" for the primitives with the said name. -- Stefano > -----Original Message----- > From: programming-boun...@forums.jsoftware.com [mailto:programming- > boun...@forums.jsoftware.com] On Behalf Of Devon McCormick > Sent: Monday, December 03, 2012 7:32 PM > To: J-programming forum > Subject: Re: [Jprogramming] @: and capped fork > > I'm sure I don't understand the Javascript-specific nuances of your question, > but is a J version much different than this? > > do_something"0 a=.
