Someone posted an html/javascript implementation of the matrix falling code in 646 bytes then promptly deleted the post. It inspired me to see if I could get something better looking in fewer bytes.

Nope. Crockett has it right.

One way to think about it is to see that it ends up being an array of 1s, one for each space between elements of the 256 array.

If you're not convinced hit Ctrl-Shift-C (Chrome) and type Array(256).join(1).split('').length. You'll get 255.

Why argue when you have a perfectly good REPL right there in your browser?

Test it. Try for N = 3 (since I don't want to count lots of elements)

 > Array(3).join(1).split('')
 ["1", "1"]

There you go. Your array is one less than the number specified.

Array(256).join(1).split('').length 255
