 The actual number of provided arguments depends on function `length`. If `reducer` accepts three arguments, `reducer` is provided `accumulator`, `value` and `next`. If `reducer` accepts four arguments, `reducer` is provided `accumulator`, `value`, `index`, and `next`. For every other `reducer` signature, `reducer` is provided all five arguments.
