shallow-clone

Make a shallow clone of an object, array or primitive.

Install

Install with npm

$ npm i shallow-clone --save

Usage

var clone = require('shallow-clone');

shallow clones arrays

The array itself is cloned, but not the elements of the array. So any objects in the array will still not be cloned (e.g. they will be the same object as in the orginal array).

var arr = [{ 'a': 0 }, { 'b': 1 }]
var foo = clone(arr);
// foo =>  [{ 'a': 0 }, { 'b': 1 }]

// array is cloned
assert.equal(actual === expected, false);

// array elements are not
assert.deepEqual(actual[0], expected[0]); // true

returns primitives as-is

clone(0)
//=> 0

clone('foo')
//=> 'foo'

shallow clone a regex

clone(/foo/g)
//=> /foo/g

shallow clone an object

clone({a: 1, b: 2, c: 3 })
//=> {a: 1, b: 2, c: 3 }
