# clone-deep [![NPM version](https://img.shields.io/npm/v/clone-deep.svg)](https://www.npmjs.com/package/clone-deep) [![Build Status](https://img.shields.io/travis/jonschlinkert/clone-deep.svg)](https://travis-ci.org/jonschlinkert/clone-deep) > Recursively (deep) clone JavaScript native types, like Object, Array, RegExp, Date as well as primitives. The `instanceClone` function is invoked to clone objects that are not "plain" objects (as defined by [](#isPlainObject)`isPlainObject`) if it is provided. If `instanceClone` is not specified, it will not attempt to clone non-plain objects, and will copy the object reference. ## Install Install with [npm](https://www.npmjs.com/) ```sh $ npm i clone-deep --save ``` ## Usage ```js var cloneDeep = require('clone-deep'); var obj = {a: 'b'}; var arr = [obj]; var copy = cloneDeep(arr); obj.c = 'd'; console.log(copy); //=> [{a: 'b'}] console.log(arr); //=> [{a: 'b', c: 'd'}] ``` ## Other object utils * [assign-deep](https://www.npmjs.com/package/assign-deep): Deeply assign the enumerable properties and/or es6 Symbol properies of source objects to the target… [more](https://www.npmjs.com/package/assign-deep) | [homepage](https://github.com/jonschlinkert/assign-deep) * [extend-shallow](https://www.npmjs.com/package/extend-shallow): Extend an object with the properties of additional objects. node.js/javascript util. | [homepage](https://github.com/jonschlinkert/extend-shallow) * [merge-deep](https://www.npmjs.com/package/merge-deep): Recursively merge values in a javascript object. | [homepage](https://github.com/jonschlinkert/merge-deep) * [mixin-deep](https://www.npmjs.com/package/mixin-deep): Deeply mix the properties of objects into the first object.
