Description

您可以像修改现有JavaScript对象一样向现有JavaScript对象添加新属性。以下是我们如何为ourDog添加"bark"属性： ourDog.bark = "bow-wow";或者我们的ourDog["bark"] = "bow-wow";现在当我们评估我们的ourDog.bark ，我们会得到他的吠声，“低头哇”。

Instructions

向myDog添加"bark"属性并将其设置为狗声，例如“woof”。您可以使用点或括号表示法。

Tests

tests:
  - text: 将属性<code>&quot;bark&quot;</code>添加到<code>myDog</code> 。
    testString: 'assert(myDog.bark !== undefined, "Add the property <code>"bark"</code> to <code>myDog</code>.");'
  - text: 不要在设置部分添加<code>&quot;bark&quot;</code>
    testString: 'assert(!/bark[^\n]:/.test(code), "Do not add <code>"bark"</code> to the setup section");'
