获取对象数组中key-value的值

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

for (var i = 0; i < array.length; i++) {
  var obj = array[i];
  var name = obj.name; // 获取name的值
  var age = obj.age; // 获取age的值
  console.log(name, age);
}

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

var names = array.map(function(obj) {
  return obj.name; // 获取name的值
});

var ages = array.map(function(obj) {
  return obj.age; // 获取age的值
});

console.log(names); // 输出 ['Alice', 'Bob', 'Charlie']
console.log(ages); // 输出 [25, 30, 35]

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

var result = array.reduce(function(acc, obj) {
  acc[obj.name] = obj.age; // 将name作为key，age作为value存入新对象
  return acc;
}, {});

console.log(result); // 输出 { Alice: 25, Bob: 30, Charlie: 35 }
