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.

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

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

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