deep-clone-json

Why use deep-clone-json? Cloning objects in JS is slow or complex. structuredClone is slow. JSON.parse(JSON.stringify) is fast but drops date structures and drops undefined values.

An ultra-fast recursive cloner specialized for serializable objects and standard types, outperforming built-in clone utilities.

⚡ Features

• Blazing-fast cloning performance
• Supports nested objects, arrays, primitives
• Safe handling of undefined and Date objects

📦 Installation

npm i deep-clone-json

🚀 Usage

import { deepClone } from 'deep-clone-json';

const original = { a: 1, b: { c: [true, undefined, new Date()] } };
const cloned = deepClone(original);
console.log(cloned);
