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) 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

$ npm i clone-deep --save

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'}]
