Benchmark: Object.assign vs. JSON String/Parse v3b

Tests:

object notation
var i = 0; var l; var n; while(i < 1000) { i++; l = { foo: 'bar', hello: [{hello: 'world', foo: 'bar'},{hello: 'world', foo: 'bar'},{hello: 'world', foo: 'bar'},{hello: 'world', foo: 'bar'}]}; }
JSON parse
var i = 0; var l; var n = '{"foo": "bar", "hello": [{"hello": "world", "foo": "bar"},{"hello": "world", "foo": "bar"},{"hello": "world", "foo": "bar"},{"hello": "world", "foo": "bar"}]}'; while(i < 1000) { i++; l = JSON.parse(n); }
Object assign
var i = 0; var l; var n = {foo: 'bar', hello: [{hello: 'world', foo: 'bar'},{hello: 'world', foo: 'bar'},{hello: 'world', foo: 'bar'},{hello: 'world', foo: 'bar'}]}; while(i < 1000) { i++; l = Object.assign({}, n); }
