Usage

Parameters

arr     (required)
options (optional) default = { step: 1, remove: true }

Requiring

const removeOffsets = require('@pelevesque/remove-offsets')

Basic

const arr = [
  'abcdef',
  '123456',
  'defabc', // 0
  'apple',
  '234561', // 1
  'banana',
  '456123', // 1
  'panama',
  'amapan' // 7
]
const offsets = removeOffsets(arr)
/*
arr = [
  'abcdef',
  '123456',
  'apple',
  'banana',
  'panama'
]
offsets = [
  'defabc',
  '234561',
  '456123',
  'amapan'
]
*/

Step Option

// Only check for offsets every 4 steps
const arr = [
  '123456789',
  'aaaabbbbb',
  'abbbbbaaa',
  'bbbbbaaaa', // 1
  '234567891', // 0
  '678912345', // 0
  '912345678'
]
const offsets = removeOffsets(arr, { step: 4 })
/*
arr = [
  '123456789',
  'aaaabbbbb',
  'abbbbbaaa',
  '912345678'
]
offsets = [
  'bbbbbaaaa',
  '234567891',
  '678912345'
]
*/

Remove Option

With the remove option set to false, offsets are still returned, but nothing is removed from the original array.

// Only check for offsets every 4 steps
const arr = [
  '123456789',
  'aaaabbbbb',
  'abbbbbaaa',
  'bbbbbaaaa', // 1
  '234567891', // 0
  '678912345', // 0
  '912345678'
]
const offsets = removeOffsets(arr, { step: 4, remove: false })
/*
arr = [
  '123456789',
  'aaaabbbbb',
  'abbbbbaaa',
  'bbbbbaaaa',
  '234567891',
  '678912345',
  '912345678'
]
offsets = [
  'bbbbbaaaa',
  '234567891',
  '678912345'
]
