# clone-deep [](https://www.npmjs.com/package/clone-deep) [](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

var obj = {a: 'b'};
|
||
|
|
var arr = [obj];
|
||
|
|
|
||
|
|
var copy = cloneDeep(arr);
|
||
|
|
obj.c = 'd';
|
||
|
|
|
||
|
|
console.log(copy);
|
||
|
|
//=> [{a: 'b'}]
|
||
|
