clone-deep

Recursively (deep) clone JavaScript native types, like Object, Array, RegExp, Date as well as primitives.

Please consider following this project's author, Jon Schlinkert, and consider starring the project to show your :heart: and support.

Install

Install with npm:

$ npm install --save clone-deep

Usage

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'}]

Heads up!

The instanceClone function is invoked to clone objects that are not "plain" objects (as defined by isPlainObjectisPlainObject) if it is provided. If instanceClone is not specified, it will not attempt to clone non-plain objects, and will copy the object reference.

Attribution

Based on mout's implementation of deepClone.
