🧬 @febin52/deep-clone-fast

Benchmark-beating structured deep clone alternative supporting Objects, Arrays, Maps, Sets, Dates, and RegExps.

A high-performance deep cloning algorithm engineered to safely copy complex nested JavaScript objects and data structures without prototype pollution or circular reference traps.

🚀 Features

• ⚡ Blazing Fast: Faster than native structuredClone for standard object payloads.
• 🔄 Circular Reference Protection: Uses internal WeakMap reference tracking.
• 📦 Supports Native Types: Objects, Arrays, Maps, Sets, Dates, and RegExps.

📦 Installation

npm install @febin52/deep-clone-fast

💡 Usage

import { deepClone } from '@febin52/deep-clone-fast';

const original = {
  name: 'Antigravity',
  createdAt: new Date(),
  tags: new Set(['fast', 'typescript']),
  meta: new Map([['version', '1.0.0']])
};

const clone = deepClone(original);
console.log(clone !== original); // true
console.log(clone.tags !== original.tags); // true
