使用Javascript Reduce处理对象

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

// 计算对象属性的总和
const totalAge = data.reduce((accumulator, currentValue) => {
  return accumulator + currentValue.age;
}, 0);
console.log(totalAge); // 输出 90

// 查找特定条件的对象
const targetObject = data.reduce((accumulator, currentValue) => {
  if (currentValue.name === 'Bob') {
    return currentValue;
  }
  return accumulator;
}, null);
console.log(targetObject); // 输出 { name: 'Bob', age: 30 }

// 将对象数组转换为其他数据结构
const nameArray = data.reduce((accumulator, currentValue) => {
  accumulator.push(currentValue.name);
  return accumulator;
}, []);
console.log(nameArray); // 输出 ['Alice', 'Bob', 'Charlie']
