假设以下是我们的第一个数组-
const firstArray = [ { "name": "John Doe" }, { "name": "John Smith" }, { "name": "David Miller" }, { "name": "Bob Taylor" }, { "name": "Carol taylor" }, { "name": "Adam Smith" }, ];
假设以下是我们的第二个数组-
const secondArray = [ { "name": "Adam Smith" }, { "name": "John Doe" }, { "name": "David Miller" }, { "name": "James Taylor" } ];
要进行比较,请使用map()
和includes()
。
以下是代码-
const firstArray = [ { "name": "John Doe" }, { "name": "John Smith" }, { "name": "David Miller" }, { "name": "Bob Taylor" }, { "name": "Carol taylor" }, { "name": "Adam Smith" }, ]; const secondArray = [ { "name": "Adam Smith" }, { "name": "John Doe" }, { "name": "David Miller" }, { "name": "James Taylor" } ]; const getAllValue = ({ 'name': name }) => name; const result = firstArray .map(getAllValue) .filter(value => secondArray .map(getAllValue) .includes(value) ); console.log(result);
要运行上述程序,您需要使用以下命令-
node fileName.js.
在这里,我的文件名为demo251.js
输出结果
这将在控制台上产生以下输出-
PS C:\Users\Amit\javascript-code> node demo251.js [ 'John Doe', 'David Miller', 'Adam Smith' ]
