Description

创建一个查看对象数组（第一个参数）的函数，并返回具有匹配的名称和值对的所有对象的数组（第二个参数）。如果要包含在返回的数组中，则源对象的每个名称和值对都必须存在于集合中的对象中。例如，如果第一个参数是[{ first: "Romeo", last: "Montague" }, { first: "Mercutio", last: null }, { first: "Tybalt", last: "Capulet" }] ，第二个参数是{ last: "Capulet" } ，然后你必须从数组（第一个参数）返回第三个对象，因为它包含名称及其值，它作为第二个参数传递。如果卡住，请记得使用Read-Search-Ask 。编写自己的代码。
