会js的大哥帮忙组装一下数组

Question

str1= ['111.jpg','2222.jpg']
str2=['1111.mp4','2222.mp4']

我想要的组装结果是：

str3=[
{"pic":"111.jpg","video":"111.mp4"} 
{"pic":"222.jpg","video","222.mp4"}
]

Answer 1

简单做法：

var str1 = ['111.jpg','2222.jpg'];
var str2 = ['1111.mp4','2222.mp4'];
var str3 = str1.map((el, index) => {
    return {
        pic: el,
        video: str2[index]
    };
});
console.log(str3);

[
  {
    "pic": "111.jpg",
    "video": "1111.mp4"
  },
  {
    "pic": "2222.jpg",
    "video": "2222.mp4"
  }
]
