将数据从数组中提取到新的自变量中-JavaScript？
为此，可以使用点（。）表示法。
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，您需要使用以下命令-
node fileName.js.
在这里，我的文件名为demo248.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 demo248.js David 27 Javascript
