I think your looking for power (^:), a conjunction though.
+: ^: (2&|)"0 i. 8
0 2 2 6 4 10 6 14
which one could read as: double (+:) if (^:) odd (2&|) for each atom ("0)
in the input (i. 8).
Note that ^: is more general than "if": in u ^: v y, u is applied (v y)
times. in the case of odd (2&|) it happens to be either 0 or 1 time.
See https://code.jsoftware.com/wiki/Vocabulary/hatco for more info.
Hope this helps!
