Script Preparation code:

// intial data
var source = {a:1,b:1,c:1,d:1,e:1,f:1,g:1,h:{a:-1,b:1,c:1,d:1,e:1,f:1,g:1}};

Tests:

Lodash
var result = _.cloneDeep(source); // adding checking to prevent compiler optimization if (result.h.a != -1) throw new Error('Object not clonned'); result.h.a = Math.random();
Ramda without relying on currying or composition
var result = R.clone(source); // adding checking to prevent compiler optimization if (result.h.a != -1) throw new Error('Object not clonned'); result.h.a = Math.random();
Fast Clone
var CloneFactory = FastClone.factory(source); var result = new CloneFactory(source); // adding checking to prevent compiler optimization if (result.h.a != -1) throw new Error('Object not clonned'); result.h.a = Math.random();
