jsoncopy  

Create a deep clone of an object using JSON functionalities. Very efficient and quick, not a comprehensive copyier (can't copy functions, circular references)

``js
const jsoncopy = require('jsoncopy');

const orig = {top: {nested: {value: 1}}};
const copy = jsoncopy(obj);
orig.top.nested.value = 2;

orig.top.nested.value // 2
copy.top.nested.value // 1
