# iterable-keyed-map

This package is a Typescript-rewriting of [anko/array-keyed-map](https://github.com/anko/array-keyed-map). With some additional tweakings and features.

```ts
import { IterableKeyedMap } from "iterable-keyed-map";

// init
const ikmap = new IterableKeyedMap<string, string | number>();

// set
ikmap.set(["1", "2", "3"], 1);
ikmap.set(["1", "2"], 2);
ikmap.set(["3", "2", "1"], "random string");

// get
console.log(ikmap.get(["1", "2"]));
console.log(ikmap.get(["1", "2", "3"]));
console.log(ikmap.get(["3", "2", "1"]));

// iterate (in insertion order)
console.log([...ikmap]);

// delete
ikmap.delete(["1", "2"]);

// iterate
console.log([...ikmap]);
```

## Features

- Fully written in Typescript.
- Pure ESM package.
- Using [class private fields](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Classes/Private_class_fields).
- The underlying tree structure is exactly the same with [anko/array-keyed-map](https://github.com/anko/array-keyed-map).
- Keeping all the APIs the same with [`Map`](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Map#instance_properties) ensured by [`implements` clauses](https://www.typescriptlang.org/docs/handbook/2/classes.html#implements-clauses).
- Iterating in insertion order.
- No dependencies.

## Todos

- [ ] ~~Support custom comparison functions.~~
- [ ] Unit tests.
- [x] Code minification. (use [esm.run](https://cdn.jsdelivr.net/npm/iterable-keyed-map/+esm))

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.

GitHub Actions: Input argument flows to dangerous sink

A GitHub context variable (such as issue title, PR description, or comment body) is being exported as an environment variable. These context values are user-controlled and could be exploited by subsequent workflow steps.

A GitHub context variable (such as issue title, PR description, or comment body) is being passed back as an output. These context values are user-controlled and could be exploited by consuming workflows.

GitHub Actions: GitHub context variable passed back as output

A GitHub context variable (such as issue title, PR description, or comment body) flows into a dangerous sink (such as shell command execution). This is a critical security issue that could allow command injection or code execution attacks.

GitHub Actions: GitHub context variable flows to dangerous sink

An environment variable flows into a dangerous sink (such as shell command execution). If this environment variable comes from an untrusted source, it could be exploited to inject commands.
