array-string-map

A Map that internally encodes Arrays to strings so that two Arrays with the same elements will return the same item.

Motivation

I was using a Map to store array values, and I kept on running into a bug where I could not get those values back. I got fed up, and then after some Googling, realized that array lookups will not work when two different arrays with the same elements are used (such as when I use array literal syntax to create them). My solution was to encode the values as string keys.

Usage

ESM modules or TypeScript scripts can just import the normal way, such as:

import ArrayStringMap from 'array-string-map'

However, for CommonJS modules, you need to use the require function, such as:

const {default: ArrayStringMap} = require("./arrayStringMap")

API

ArrayStringMap

A class that implements the Map interface. All methods that can be used on a Map are available on the ArrayStringMap.
