Line 1,323:
J is array-oriented, so there is very little need for loops. For example, one could satisfy this task this way:
<syntaxhighlight lang=J> ,. i. -11
10
9
8
7
6
5
4
3
2
1
0
</syntaxhighlight>
J does support loops for those times they can't be avoided (just like many languages support gotos for those time they can't be avoided).
