How to iterate and assign values in a JSON array?

To iterate and assign values in a JSON array, you can use a for loop or the forEach method to iterate through each element in the array and manipulate it as needed.

Here is an example of traversing a JSON array and assigning values using a for loop.

var jsonArray = [
  {"name": "Alice", "age": 25},
  {"name": "Bob", "age": 30},
  {"name": "Charlie", "age": 35}
];

for (var i = 0; i < jsonArray.length; i++) {
  var obj = jsonArray[i];
  // 对每个元素进行赋值操作
  obj.name = "New Name";
  obj.age = 0;
}

Here is an example of traversing a JSON array and assigning values using the forEach method:

var jsonArray = [
  {"name": "Alice", "age": 25},
  {"name": "Bob", "age": 30},
  {"name": "Charlie", "age": 35}
];

jsonArray.forEach(function(obj) {
  // 对每个元素进行赋值操作
  obj.name = "New Name";
  obj.age = 0;
});

In both methods, you can define the assignment operations needed for the elements yourself.
