如何为数组中的每个对象添加新字段？

const array = [
  { name: 'John', age: 25 },
  { name: 'Jane', age: 30 },
  { name: 'Bob', age: 40 }
];

const newField = 'occupation';
const fieldValue = 'Engineer';

array.forEach(obj => {
  obj[newField] = fieldValue;
});

console.log(array);

[
  { name: 'John', age: 25, occupation: 'Engineer' },
  { name: 'Jane', age: 30, occupation: 'Engineer' },
  { name: 'Bob', age: 40, occupation: 'Engineer' }
]
