Installation

``
npm i -S clones
`

Usage

`js
const clones = require('clones')
const dest = clones(source, [bind])
`

Parameters

Parameters

source: Object, clone source

bind: Object, bind functions to this context

Returns: Any, deep clone of source

Example:
`js
const clones = require('clones')

var source = {
obj: {a: {b: 1}},
arr: [true, 1, {c: 'dee'}],
fn: function () { return this.number + 12 }
}
// adding circularity
source.obj.a.e = source.obj.a

// do the cloning (with binding a context)
var dest = clones(source, {number: 30})
// => { obj: { a: { b: 1, e: [Circular] }, d: 2017-02-17T21:57:44.576Z },
// arr: [ true, 1, { c: 'dee' } ],
// fn: [Function: fn] }

// checks
assert.ok(dest !== source) // has different reference
assert.ok(dest.obj !== source.obj) // has different reference
assert.ok(dest.obj.a !== source.obj.a) // has different reference
assert.ok(dest.obj.a.e !== source.obj.a.e) // different references for circularities
assert.equal(dest.obj.d.toISOString(),
source.obj.d.toISOString()) // has same content
assert.ok(dest.fn !== source.fn) // has different function reference
source.fn = source.fn.bind({number: 29}) // bind this for source
assert.equal(dest.fn(), source.fn() + 1) // returning the same result
`

$3

`js
const clones = require('clones')
// clone built in Array
const C = clones.classes(Array)

let c = new C(1,2,3)
// => [1, 2, 3]
c.reverse()
// => [3, 2, 1]
