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). -- cgit v1.2.3
