Hi David :) thanks for the links !
You are right, it's generally about data. Serialize an object to JSON prevent from sharing references. On the twitter feed Jeremy talks about optimizing the process . I'm agree with that, for performance and a nicer syntax. By the way, the Object.deepFreeze is really interesting , especially for an API and when you want to set some "private" properties . But I think it is a workaround to the issue of cloning because you can't freeze all objects and maybe you want to have a mutable object but cloning it afterward. 2014-06-11 9:58 GMT+02:00 David Bruant <[email protected]>: > Hi Maxime, > > Good to see you here :-) > > This topic has been discussed recently on Twitter.
