ez-array-update
Immutably update an element in an array
This library allows you to update an element in an array with immutability in mind
Install
$ npm install ez-array-update
$yarn add ez-array-update
Usage
You can update arbitrary data like numbers/strings
import updateArray from 'ez-array-update'
const sampleArray = [1, 2, 3, 4, 5]
// Change element `1` to 100
const filter = element => element === 1
const dataToUpdateTo = 100
const newNumberArray = updateArray(sampleArray, filter, dataToUpdateTo) // [100, 2, 3, 4, 5]
It also supports objects (Note: It will merge objects using spreads so it will only do a shallow merge)
import updateArray from 'ez-array-update'
const arrOfObjects = [
{ name: 'James', age: 21 },
{ name: 'Rob', age: 25 },
{ name: 'Tegan', age: 22 },
{ name: 'Alex', age: 21 },
{ name: 'Kacee', age: 25 }
]
const filter = element => element.name === 'James'
const data = { age: 240 } // You can pass in the keys you only wish to update
const newFriends = updateArray(arrOfObjects, filter, data)
