将参数从单变量数组传递给mixin

function mixin(params, target) {
  // 遍历参数数组
  for (let i = 0; i < params.length; i++) {
    const param = params[i];
    // 遍历参数对象的属性
    for (let key in param) {
      // 将属性和对应的值合并到目标对象中
      target[key] = param[key];
    }
  }
}

const targetObj = {
  name: 'John',
  age: 25
};

const params = [
  { gender: 'male' },
  { occupation: 'developer' },
  { hobbies: ['coding', 'reading'] }
];

mixin(params, targetObj);

console.log(targetObj);
// 输出：
// {
//   name: 'John',
//   age: 25,
//   gender: 'male',
//   occupation: 'developer',
//   hobbies: ['coding', 'reading']
// }
