Script Preparation code:

var arr = [31,12321,213,21321,321321,321321,1];
var processFunc = a => a + 1;

Tests:

caching variable (for global)
for (let i = arr.length, tmp; i--;) { processFunc(tmp = arr[i]); processFunc(tmp); processFunc(tmp); };
single access cache
for (let i = arr.length; i--;) { let tmp = arr[i]; processFunc(tmp); processFunc(tmp); processFunc(tmp); };
zero cache - 3x access
for (let i = arr.length; i--;) { processFunc(arr[i]); processFunc(arr[i]); processFunc(arr[i]); };
