NOTE: This library was conceived as an exercise, using functional programming, TDD and rollup.js.

A small utility library for converting arrays into a "stepped arrays".

A stepped array is an array where each member is a sub-array of the original, the first member is [1], the second is [1 ➜ 2] and the last member is [1 ➜ n].

For an example, if our input is [1, 2, 3, 4], our output will be:

[
  [1],
  [1, 2],
  [1, 2, 3]
  [1, 2, 3, 4]
]

Installation

npm i --save @eidellev/nahman
# or
yarn add @eidellev/nahman

import nahman from '@eidellev/nahman';

nahman.toSteps([1, 2, 3, 4]);
nahman.toStepsRight([1, 2, 3, 4]);

• toSteps - Converts an array into a stepped array
• toStepsRight - Converts an array into a stepped array from right to left, e.g:
