🧩 HashableObject

A small JavaScript utility built just for fun and curiosity, inspired by Java-style object hashing and equality checking.

HashableObject lets you wrap any object or array and generate a consistent, order-independent "hash" (actually a string representation) for deep comparison. It's not meant to be a cryptographic hash or production-grade tool—just a little experiment to explore object uniqueness, equality, and caching techniques.

🚀 Why?

This was a personal side project—born from a moment of curiosity:
“How would Java-style object hashing look like in JavaScript?”

I wanted to see if I could:

• Generate consistent string representations of objects regardless of key order
• Compare deeply nested structures easily
• Play around with caching, stringifying, and custom equality logic

✨ Features

• 🔍 Deep uniqueness string generation
• 💾 Cached uniqueness value on creation
• 📦 Supports objects, arrays, and nested combinations
• 🎭 Equality comparison via .equals()
• 🧵 toString() output for better debugging

📦 Example

import { HashableObject } from "./HashableObject.js";

const a = new HashableObject({ b: 2, a: 1 });
const b = new HashableObject({ a: 1, b: 2 });

console.log(a.equals(b)); // true
console.log(String(a)); // Hashable(a:1|b:2)

⚠️ Not for Production™

This isn’t optimized for performance, and it doesn't use true hashing algorithms. Think of it more as a toy, a thought experiment, or something you might use in small personal tools.

But works well for:

• Object comparisons

• Simple memoization

• Debugging or testing utilities
