Immutable Sorted Map

     

Ever wish Immutable.js Maps would insert new items sorted by key?
Issue #88 inspired me to extend Immutable's Map to do just this.

Installation

Using npm:
$ npm install immutable-sorted-map
Using yarn:
$ yarn install immutable-sorted-map

Usage

``javaScript
import SortedMap from 'immutable-sorted-map'

const myData = {
'0.01': 'hundredth',
'0.001': 'thousandth',
'0.1': 'tenth'
}

const compareKeys = (currKey, nextKey) => {
const currNum = Number(currKey)
const nextNum = Number(nextKey)
if (currNum < nextNum) return -1
if (currNum > nextNum) return 1
return 0
}

const myImmutableData = new SortedMap(myData, compareKeys)

myImmutableData.toJS()
/* {
'0.001': 'thousandth',
'0.01': 'hundredth',
'0.1': 'tenth'
} */
``
