Store information about any JS value in a side channel, using a linked list.
Warning: this implementation will leak memory until you `delete` the `key`.
Use [`side-channel`](https://npmjs.com/side-channel) for the best available strategy.
## Getting started
```sh
npm install --save side-channel-list
```
## Usage/Examples
```js
const assert = require('assert');
const getSideChannelList = require('side-channel-list');
const channel = getSideChannelList();
const key = {};
assert.equal(channel.has(key), false);
assert.throws(() => channel.assert(key), TypeError);
channel.set(key, 42);
channel.assert(key); // does not throw
assert.equal(channel.has(key), true);
assert.equal(channel.get(key), 42);
channel.delete(key);
assert.equal(channel.has(key), false);
assert.throws(() => channel.assert(key), TypeError);
```
## Tests
Clone the repo, `npm install`, and run `npm test`
