在object - javascript中迭代对象数组？

const arr = [
  { name: 'Alice', age: 25 },
  { name: 'Bob', age: 30 },
  { name: 'Charlie', age: 35 }
];

for (let i = 0; i < arr.length; i++) {
  console.log(arr[i].name, arr[i].age);
}

const arr = [
  { name: 'Alice', age: 25 },
  { name: 'Bob', age: 30 },
  { name: 'Charlie', age: 35 }
];

arr.forEach((item) => {
  console.log(item.name, item.age);
});

const arr = [
  { name: 'Alice', age: 25 },
  { name: 'Bob', age: 30 },
  { name: 'Charlie', age: 35 }
];

for (const item of arr) {
  console.log(item.name, item.age);
}

const arr = [
  { name: 'Alice', age: 25 },
  { name: 'Bob', age: 30 },
  { name: 'Charlie', age: 35 }
];

const newArr = arr.map((item) => {
  return item.name + ', ' + item.age;
});

console.log(newArr);
