 ## 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.

 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:

 ```ts
 import ArrayStringMap from 'array-string-map'
 ```

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

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

 ## API

 ### ArrayStringMap

 A class that implements the [Map](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map)
 interface. All methods that can be used on a Map are available on the ArrayStringMap.
