var obj = { a: 3, b: 4, c: [5,6] };
var dup = copy(obj);
dup.b *= 111;
dup.c.push(7);

console.log('original: ', obj);
console.log('copy: ', dup);

and you can copy arrays shallowly:

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

var xs = [ 3, 4, 5, { f: 6, g: 7 } ];
var dup = copy(xs);
dup.unshift(1, 2);
dup[5].g += 100;

console.log('original: ', xs);
console.log('copy: ', dup);

methods

var copy = require('shallow-copy')

copy(obj)

Return a copy of the enumerable properties of the object obj without making copies of nested objects inside of obj.

If obj is an array, the result will be an array. If obj is an object, the result will be an object. If obj is not an object, its value is returned.
