Add Map.rename, Array.move, and more

Added

rename

Renames the given key with the new key if found, keeping the original insertion order.

given.map({ one: 1, to: 2, three: 3 })
  .rename('to', 'two')
  .keys() // ['one', 'two', 'three']

move

Moves an item in the array using the given source index to either "before" or "after" the given target.

given.array(['b', 'a', 'c']).move(0, 'after', 1) // ['a', 'b', 'c']
given.array(['b', 'a', 'c']).move(0, 'before', 2) // ['a', 'b', 'c']
given.array(['b', 'a', 'c']).move(1, 'before', 0) // ['a', 'b', 'c']

Pointer API additions

value

Returns the value for current pointer position.

given.array(['music', 'tech']).at(1).value() // ['music', 'tech']

step

Steps forward or backwards given the number of steps.

given.array(['music', 'tech']).at(1).step(-1).value() // ['music']

Fixes

• The callback in Array.reject now accepts the index as the second argument
