zipToObject

• zipToObject

Input two arrays keys and values, and return a plain object where elements of keys serve as keys and elements of values serve as values.

Optional parameters getKey and getValue can be provided to transform elements of the objects into keys and values, respectively.

These can be field paths of getByPath or callback functions.

Added in v0.0.1
