2.0.0 (08/23/2018)

Breaking changes

• library functions now accept iterators prototyped as f(v, k, ...) instead of f(k, v, ...). It improves the benefits of chaning and helps writting a clear functional-style code. Library functions affected with this breaking change are : each, eachi,countf, map, reduceby, select, reject, all, groupBy, countBy, selectWhile, dropWhile, findIndex, findLastIndex, chunk.
• reduceby is now prototyped as reduceby(t, f, pred, state) instead of reduceby(t, f, state, pred).
• times is now prototyped as times(iter, n, ...) instead of times(iter, n, ...).
• bindAll was renamed to bindall
• functions no longer accept optional sort third arguments
• sliding was renamed to overlapping
• Improved range to handle negative progressions and start the count from 1.
• memoize no longer takes a hash function.

Other changes

• Made shift a default library function, and pop its alias.
• Moved shuffle from table function to array functions
• Made iterator to accept an extra optional arg n
