无法理解这个原型概念

Not able to understand this prototype concept

我正在浏览 article` 时遇到了这段代码, 它在哪里解释原型及其工作原理。 我要的是,这句话相对于代码是什么意思。

This code creates a Date object, then walks up the prototype chain, logging the prototypes. It shows us that the prototype of myDate is a Date.prototype object, and the prototype of that is Object.prototype

const myDate = new Date();
let object = myDate;

do {  
  object = Object.getPrototypeOf(object);
  console.log(object);

} while (object);

其实很简单:

const myDate = new Date();   // Create a Date object.
let object = myDate;

do {  
  object = Object.getPrototypeOf(object); // Find the object’s prototype.
  console.log(object);                    // Print to the log.
} while (object);            // Repeat (finding prototypes’ prototypes)
                             // as long as there are prototypes to be found.

所以,我们会发现对象的原型有一个原型。这就是摘录中提到的链条。
