array-map-slice

Allows to map a slice of the array for each item in the array.

Usage

const mapSlice = require('array-map-slice');

mapSlice([ 1, 2, 3 ], (slice, index, array) => {
    return slice.join('-');
});
// => [ '1', '1-2', '1-2-3' ]

Or if you want to create slices from the right use mapSliceRight:

const mapSlice = require('array-map-slice');

mapSlice.mapSliceRight([ 1, 2, 3 ], (slice, index, array) => {
    return slice.join('-');
});
// => [ '1-2-3', '2-3', '3' ]
