A useful tip I picked up was to use
ii
instead ofj
for an inner loop. It's far more distinct thanj
.If for some terrible reason you have even more inner loops you can easily continue the trend
i
,ii
,iii
,iiii
,iiiii
- oriv
,v
if you're feeling romanWhen you have multiple indices you're also bound to have multiple cardinals those indices count up to, say
foo.length
andbar.length
, sofoo_i
andbar_i
are perfectly legible and self-documenting. A bit Hungarian but Hungarian is good in small amounts. Unless you're dealing withwidth
andheight
in which case it'sx
andy
but it's not thatwidth_i
would be incomprehensible.
