keyed-array

keyed-array

Recursively add named keys to arrays of objects

I wrote a blog post about the idea here: http://zeke.sikelianos.com/keyed-arrays-in-javascript

Installation

npm install keyed-array --save

Usage

For more extensive usage examples, see test.js

const keyedArray = require('keyed-array')

let people = [
  {id: 'bob', name: 'Bob', isCool: false},
  {id: 'sue', name: 'Sue', isCool: false},
  {id: 'hal', name: 'Hal', isCool: true},
  {id: 'ann', name: 'Ann', isCool: true}
]

people = keyedArray(people)

// `people` is still an array, but now it also has keys based on the `id`
// value of each object
people.bob
// {id: 'bob', name: 'Bob', isCool: false}
