@magic/deep

Work with deeply nested objects and arrays.

install

npm i --save --save-exact @magic/deep

import

// single function
import { equal, flatten, loop, merge } from '@magic/deep'

// object with all functions
import deep from '@magic/deep'

Currently implemented:

deep.equal

// test equality
deep.equal(['shallow', ['deep']], ['shallow', ['deep']])
// true

// alias
deep.equals, deep.eq

deep.different

// test difference
deep.different(['shallow', ['deep']], ['shallow', ['deep']])
// false

// alias
deep.diff

deep.flatten

// flatten a deeply nested array
deep.flatten(['shallow', ['deep']])
// ['shallow', 'deep']

deep.loop

// apply function add
const add = e => e + 1

// for each item
const items = [1, 2, [3]]

// using a deeply nested array
deep.loop(add, items)
// or
deep.loop(items, add)
// returns [2, 3, [4]]

deep.merge

// merge objects and arrays, with infinite recursion if needed.
// this can be slow...

deep.merge({ obj1Key: { val: 1 } }, { obj2Key: { val: 2 } } )

// { obj1Key: { val: 1}, obj2Key: { val: 2 } }

deep.merge({ key: { val: 1, str: 'test' } }, { key: { val: 2, str: 'overwritten' } })

// { key: { val: 2, str: 'overwritten' } }
