获取数组的属性并将其写入新数组(JS)

var oldArray = [{name: 'John', age: 25}, {name: 'Jane', age: 30}];
var newArray = [];

for (var i = 0; i < oldArray.length; i++) {
  newArray.push(oldArray[i].name); // 获取name属性并写入新数组
}

console.log(newArray); // 输出: ['John', 'Jane']

var oldArray = [{name: 'John', age: 25}, {name: 'Jane', age: 30}];

var newArray = oldArray.map(function(item) {
  return item.name; // 获取name属性并写入新数组
});

console.log(newArray); // 输出: ['John', 'Jane']
