!Libraries.io dependency status for latest release

Functions for representing plain objects as typesafe immutable dictionaries

Getting started

``
npm i ts-micro-dict
`

Usage

`typescript
import { Dict } from 'ts-micro-dict'
import { pipeWith } from 'pipe-ts'

const dict: Dict = { x: 1 } // Readonly>

// put

const putDict = Dict.put('y', 1, dict) // Dict
const putCurried = pipeWith(dict, Dict.put('y', 3)) // Dict

// omit

const omitDict = Dict.omit('x', dict) // Dict
const omitCurried = pipeWith(dict, Dict.omit('x')) // Dict

// filter

const filterDict = Dict.filter((item, key) => true, dict) // Dict
const filterCurried = pipeWith(
dict,
Dict.filter((item, key) => true)
) // Dict

// map

const mapDict = Dict.map((item, key) => true, dict) // Dict
const mapCurried = pipeWith(
dict,
Dict.map((item, key) => true)
) // Dict

// reduce

const reduceDict = Dict.reduce((acc, item, key) => acc + item, 0, dict) // number
const reduceCurried = pipeWith(
dict,
Dict.reduce((acc, item, key) => acc + item, 0)
) // number

// some

const someDict = Dict.some((item, key) => true, dict) // boolean
const someCurried = pipeWith(
dict,
Dict.some((item, key) => true)
) // boolean

// every

const everyDict = Dict.every((item, key) => true, dict) // boolean
const everyCurried = pipeWith(
dict,
Dict.every((item, key) => true)
) // boolean

// toArray

const toArray = Dict.toArray((item, key) => [key, item], dict) // readonly (readonly [string, number])[]
const toArrayCurried = pipeWith(
dict,
Dict.toArray((item, key) => [key, item])
) // readonly (readonly [string, number])[]

// fromArray

const array: number[] = [1, 2, 3]
const fromArray = Dict.fromArray((value, index) => [${index}, value], array) // Dict
const fromArrayCurried = pipeWith(
array,
Dict.fromArray((value, index) => [${index}, value])
) // Dict

// length

const length = Dict.length(dict) // number

// isEqual

const isEqual = Dict.isEqual(dict, { y: 2 }, (a, b) => a === b) // false˜
