Join

-

Join (∾) is an extension of the monadic function Raze from A+ and J to arbitrary argument ranks. It has the same relationship to Join to, the dyadic function sharing the same glyph, as Merge (>) does to Couple (≍): a≍b is >a‿b and a∾b is ∾a‿b. While Merge and Couple combine arrays (the elements of Merge's argument, or the arguments themselves for Couple) along a new leading axis, Join and Join to combine them along the existing leading axis. Both Merge and Join can also be called on a higher-rank array, causing Merge to add multiple leading axes while Join combines elements along multiple existing axes.

Join can be used to combine several strings into a single string, like array.join() in Javascript (but it doesn't force the result to be a string).
