Description

有时检查给定对象的属性是否存在是有用的。我们可以使用对象的.hasOwnProperty(propname)方法来确定该对象是否具有给定的属性名称。 .hasOwnProperty()如果找到属性则返回true或false 。例

var myObj = {
顶部：“帽子”，
底部：“裤子”
};
myObj.hasOwnProperty（ “顶部”）; //真的
myObj.hasOwnProperty（ “中间”）; //假

Instructions

修改函数checkObj以测试myObj的checkProp 。如果找到该属性，则返回该属性的值。如果没有，请返回"Not Found" 。

Tests

tests:
  - text: <code>checkObj(&quot;gift&quot;)</code>应该返回<code>&quot;pony&quot;</code> 。
    testString: assert(checkObj("gift") === "pony");
  - text: <code>checkObj(&quot;pet&quot;)</code>应该返回<code>&quot;kitten&quot;</code> 。
    testString: assert(checkObj("pet") === "kitten");
  - text: <code>checkObj(&quot;house&quot;)</code>应该返回<code>&quot;Not Found&quot;</code> 。
    testString: assert(checkObj("house") === "Not Found");

Challenge Seed

// Setup
var myObj = {
  gift: "pony",
  pet: "kitten",
  bed: "sleigh"
};

function checkObj(checkProp) {
  // Your Code Here

  return "Change Me!";
}

// Test your code by modifying these values
checkObj("gift");
