Get or Set Anything 🐊

``
npm i getorset-anything
`

Get a Map/Obj value, or if it didn't exist yet set it and return that. Fully TypeScript supported! A simple & small integration.

Motivation

I created this package because I always hated doing this over and over again:

`ts
const map = new Map()

const id = 'abc'

let arr = map.get(id)
if (arr === undefined) {
arr = []
map.set(id, arr)
}

arr.push(100)
`

So that is exactly what getorset-anything does for you! 💯

getorset-anything has performance in mind. It won't do a .has() check, like other libraries do, when it found the value it will immediately return it.

Usage

Maps

`ts
import { mapGetOrSet } from 'getorset-anything'

const map = new Map()

const arr = mapGetOrSet(map, 'abc', (): number[] => [])

arr.push(100) // OK!
`

Objects

`ts
import { objGetOrSet } from 'getorset-anything'

const obj: Record = {}

const arr = objGetOrSet(obj, 'abc', (): number[] => [])

arr.push(100) // OK!
`

TypeScript Support

You don't have to do anything extra for TypeScript! It comes with awesome type support.

`ts
import { mapGetOrSet } from 'getorset-anything'

const map = new Map()

const arr = mapGetOrSet(map, 'abc', () => []) // OK!
const arr2 = mapGetOrSet(map, 'abc', () => ({})) // NG! ⛔️

arr.push(100) // OK!
arr.push('100') // NG! ⛔️
