shallow-clone 
Make a shallow clone of an object, array or primitive.
Install
Install with npm:
$ npm install --save shallow-clone
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 }
