 # orb-array
-*orb-array* aims to simplify common array operations that use functional programming constructs. The usage of map, reduce, filter, fill etc. APIs is often verbose. Our goal is to make their usage *less-verbose*

 ## APIs
 ### split
-It splits an array into specified number of pieces. When the number of pieces is larger than the input size, it creates empty pieces. It always returns the specified number of pieces. Following are some examples:
