Weak-Ref-Cache

The weak-ref-cache package is a utility module designed to help you manage and reuse weak references to objects in JavaScript. With this package, you can retrieve weak references to objects and compare them using the same equality comparison as you would use for the objects themselves. Furthermore, it ensures that only one WeakRef instance is created per object, promoting memory efficiency.

Installation

``bash
npm install weak-ref-cache
`

Usage

Here's how you can use the weak-ref-cache package:

1. Import the getWeakRef function from the package.
2. Use the getWeakRef function to get a weak reference to an object.
3. You can compare weak references obtained using the getWeakRef function just like you would compare the objects themselves.

$3

`ts
import getWeakRef from "weak-ref-cache";

const obj = { foo: "bar" };

const weakRef = getWeakRef(obj);

console.log(weakRef === getWeakRef(obj)); // true

console.log(weakRef === new WeakRef(obj)); // false
`

API

$3

- Parameters:
- obj (Object): The object for which you want to get a weak reference.
- Returns:
- A WeakRef instance representing a weak reference to the obj. If a weak reference to the obj was previously created by getWeakRef, it returns the same WeakRef` instance.
