javascript - 在 d3.js 中改变对象的 [[prototype]] 的警告？

Question

我正在使用 d3.js 进行数据可视化。我收到下图中显示的警告。 有谁知道为什么会这样，我该如何解决？错误中显示的消息如下

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

Answer 1

Does anyone have the idea why is this happening

看起来是 d3 的错。他们似乎用它来子类化数组 here :

// Until ECMAScript supports array subclassing, prototype injection works well.
var d3_subclass = function(object, prototype) {
  object.__proto__ = prototype;
};

how can I solve this?

忽略警告。或者提交错误看看this issue d3.js 的。
