plotly is using __proto__ which slows down the script?!

[marcinwojciechowski]

Hello,
I have found that in FF browser i got a warning telling:
"mutating the [[Prototype]] of an object will cause your code to run very slowly; instead create the object with the correct initial [[Prototype]] value using Object.create"

When I search the net what does that means I have found this stackoverflow ticket: http://stackoverflow.com/questions/23807805/why-is-mutating-the-prototype-of-an-object-bad-for-performance

Can you say something about that? Does it really impact the performance?

Best regards,
Marcin

It appears to be a d3 3.x issue which I would hazard to guess is aggressively worded to encourage "best practices". I'd be surprised if it actually has much of an effect except in very pathological cases. At any rate, there will be no fix for d3 3.x, so I don't think there's anything to be done about this.
