nanoclone

What is nanoclone?

The nanoclone npm package is a lightweight utility for deep cloning JavaScript objects. It is designed to be simple and efficient, making it a useful tool for copying objects without retaining references to the original objects.

What are nanoclone's main functionalities?

Deep Cloning

This feature allows you to create a deep copy of an object, ensuring that nested objects are also cloned and not just referenced.

const clone = require('nanoclone');
const original = { a: 1, b: { c: 2 } };
const copy = clone(original);
console.log(copy); // { a: 1, b: { c: 2 } }
console.log(copy.b === original.b); // false

Other packages similar to nanoclone

lodash.clonedeep

Lodash's `cloneDeep` function provides similar functionality for deep cloning objects. It is part of the larger Lodash utility library, which offers a wide range of functions for manipulating and traversing data structures. Compared to nanoclone, lodash.clonedeep is more feature-rich but also larger in size.

rfdc

The `rfdc` (Really Fast Deep Clone) package is another alternative for deep cloning objects. It is designed to be extremely fast and efficient, making it a good choice for performance-critical applications. Like nanoclone, it focuses solely on deep cloning, but it is optimized for speed.

clone-deep

The `clone-deep` package is another utility for deep cloning objects. It supports cloning of various data types, including arrays, buffers, and more. It is more versatile than nanoclone but also slightly larger in size.
