Usage

Default:

// CJS require
const NeuPack = require('neupack')
// ESM import
import NeuPack from 'neupack'

const items = [
  { id: 'ID3', name: 'Name 1', rel: '1574' },
  { id: 'ID2', name: 'Name 2', rel: '1574' }
]
const pack = new NeuPack({
  input: items,
  id: 'id'
})

pack.includes('Name 1')
pack.filter(el => el.rel === '1574')
pack.edit('NM587', { rel: '2000' })
pack.delete('NM202')
pack.push({ id: 'NM456', name: 'NeuTest', rel: '2020' })

for (const el of pack) {
  // do something with el
}

const arr = await pack.all(async el => {
  // do something async with el
})

const arr = await pack.allSettled(async el => {
  // do something async with el
})

const arr = await pack.any(async el => {
  // do something async with el
})

const arr = pack.map(el => {
  // do something with el
})

const result = pack.some(el => {
  // do something with el
})

pack.each(el => {
  // do something with el
})

const packGenerator = pack.generator // get generator
packGenerator.next() // get next { value, done }

Static:

// CJS require
const NeuPack = require('neupack')
// ESM import
import NeuPack from 'neupack'

const items = [
  { id: 'ID3', name: 'Name 1', rel: '1574' },
  { id: 'ID2', name: 'Name 2', rel: '1574' }
]

NeuPack.each(items, (el, i) => {
  console.log(el)
})

const packMap = NeuPack.map(items, (el, i) => {
  return el
})

const packValuedMap = NeuPack.valuedMap(items, (el, i) => {
  return el || null
})

/**
 * Awaits for each callback to finish.
 * Similar to [ await Promise.all(items.map(asyncFn)) ]
 */
const packPack = await NeuPack.pack(items, async (el, i) => {
  return el
})

const packToObject = NeuPack.toObject(items, 'id')

/**
 * Runs callback on each element while in reverse and reverses the array back on return.
 */
const packReverseBack = NeuPack.reverseBack(items, (el, i) => {
  return el
})
