The most convenient and accurate cloner for node.js. It's also very fast in some cases (benchmarks inside).
npm install node-v8-clone
It's a c++ addon for node.js that does the most accurate cloning for node.js.
It's also very fast in some cases (benchmarks inside).
Tested on node.js versions 0.8, 0.9, 0.10 and 0.11.13 (prior 0.11.x versions are not compatible).
You may be asked to install make and g++ as well.
```
npm install node-v8-clone
`javascript
var clone = require('node-v8-clone').clone;
var a = { x: { y: {} } };
// deep clone
var b = clone(a, true);
a === b // false
a.x === b.x // false
a.x.y === b.x.y // false
// shallow clone
var c = clone(a, false);
a === c // false
a.x === c.x // true
a.x.y === c.x.y // true
``
Extended syntax:javascript
var Cloner = require('node-v8-clone').Cloner;
var a = [1, [2, 3, 4], 5];
// create a cloner instance for deep cloning optimized for arrays.
var c = new Cloner(true, { 'Array': Cloner.deep_array });
var b = c.clone(a);
a === b // false
a[1] === b[1] // false
