JavaScript 将数据从数组中拉到新的独立变量中

对于这一点，你可以使用dot(.)符号。

示例

以下是代码 –

const employeeDetails = [
   {
      employeeName: "Chris",
      employeeAge: 25,
      employeeTechnology: "Java"
   },
   {
      employeeName: "David",
      employeeAge: 27,
      employeeTechnology: "Javascript"
   },
   {
      employeeName: "Bob",
      employeeAge: 24,
      employeeTechnology: "Python"
   }
]
var firstName = employeeDetails[1].employeeName;
var age = employeeDetails[1].employeeAge;
var technology = employeeDetails[1].employeeTechnology; 
console.log(firstName);
console.log(age);
console.log(technology);

要运行上述程序，你需要使用以下命令—-。

node fileName.js.

在这里，我的文件名是demo248.js。

输出

这将在控制台产生以下输出 –

PS C:\Users\Amit\javascript-code> node demo248.js
David
