side-channel 1.0.3

The "side-channel" is a noteworthy npm package in JavaScript that facilitates storing information about any JavaScript value in a side channel. Notably, it leverages the WeakMap if accessible. Using side-channel has been a go-to solution for many developers aiming to increase the efficiency of their JavaScript code by storing and retrieving data on the fly.

To use side-channel, you first need to install the package from npm using the typical installation command line: npm install side-channel. Once installed, it can be imported into your JavaScript file using either RequireJS or ES6 import. Here is a basic example of how you can use side-channel:

// Import SideChannel with RequireJS
const SideChannel = require('side-channel');

// Or with ES6
import SideChannel from 'side-channel';

// Set up a new SideChannel
const sideChannel = new SideChannel();

const obj = {};

// Set a SideChannel value
sideChannel.set(obj, 'Hello world!');

// Get a SideChannel value
console.log(sideChannel.get(obj)); // Prints: 'Hello world!'

In this example, a new SideChannel object is created, then a value ('Hello world!') is set for a JavaScript object (obj). This value is then retrieved and logged.
