Script Preparation code:
var obj = {a: "hello", c: "test", po: 33, arr: [1, 2, 3, 4], anotherObj: {a: 33, str: "whazzup"}}; var myCopy = null;
Tests:
JSON Stringfy
myCopy = JSON.parse(JSON.stringify(obj));
Lodash cloneDeep
myCopy = _.cloneDeep(obj);
Ramda Copy
myCopy = R.clone(obj);
Recursive Copy
var deepCopy = function(obj) { var out = Array.isArray(obj) ? [] : {}; for (var key in obj) { var v = obj[key]; out[key] = (typeof v === 'object') ? deepCopy(v) : v; } return out; }; myCopy = deepCopy(obj);
Recursive Copy Distinct
var deepCopy = function(block) { var out = null; if (Array.isArray(block)) { out = []; for (var index = 0; index < block.length; ++index) { var subArray = block[index]; out.push((typeof subArray === 'object') ? deepCopy(subArray) : subArray); } } else { out = {}; for (var key in block) { var subObject = block[key]; out[key] = (typeof subObject === 'object') ? deepCopy(subObject) : subObject; } } return out; }; myCopy = deepCopy(obj);
