删除JSON元素-JavaScript？

假设以下是我们的JSON字符串-

var details =
[
   {
      customerName: "Chris",
      customerAge: 32
   },
   {
      customerName: "David",
      customerAge: 26
   },
   {
      customerName: "Bob",
      customerAge: 29
   },
   {
      customerName: "Carol",
      customerAge: 25
   }
]

要删除JSON元素，请在JavaScript中使用delete关键字。

示例

以下是删除JSON元素的完整代码-

var details =
[
   {
      customerName: "Chris",
      customerAge: 32
   },
   {
      customerName: "David",
      customerAge: 26
   },
   {
      customerName: "Bob",
      customerAge: 29
   },
   {
      customerName: "Carol",
      customerAge: 25
   }
]
delete details[0].customerAge;
console.log(details);

要运行以上程序，您需要使用以下命令-

node fileName.js.

在这里，我的文件名为demo211.js-

PS C:\Users\Amit\JavaScript-code> node demo211.js
[
   { customerName: 'Chris' },
   { customerName: 'David', customerAge: 26 },
   { customerName: 'Bob', customerAge: 29 },
   { customerName: 'Carol', customerAge: 25 }
]
