Cloning: what's the fastest alternative to JSON.parse(JSON.stringify(x))?

Question

What\'s the fastest alternative to

JSON.parse(JSON.stringify(x))

There must be a nicer/built-in way to perform a deep clone on objects/arrays,

Answer 1

I was actually comparing it against angular.copy

You can run the JSperf test here: https://jsperf.com/angular-copy-vs-json-parse-string

I'm comparing:

myCopy = angular.copy(MyObject);

vs

myCopy = JSON.parse(JSON.stringify(MyObject));

This is the fatest of all test I could run on all my computers
