怎么合并两个数组

Question

怎么合并两个数组呢，把data2里对应id的remark放进data1对应的id这里面，最终效果就是data3这样
constdata1=[
{"id":1,"url":"1111"},
{"id":2,"url":"111"},
{"id":3,"url":"22222"},
{"id":4,"url":"222"},
{"id":5,"url":"2222"},
{"id":6,"url":"22222是"}
]
constdata2=[
{"id":1,"remark":"备注1"},
{"id":2,"remark":"备注2"},
{"id":3,"remark":""},
{"id":4,"remark":""},
{"id":5,"remark":""},
{"id":6,"remark":"beizhu6"}
]
functionfun(arr1,arr2){
arr1.map(item=>{
arr2.map(item2=>{
if(item.id==item2.id){
}
});
});
arr2=[];
returnarr1
}
fun(data1,data2);
data3=[
{"id":1,"url":"1111","remark":"备注1"},
{"id":2,"url":"111","remark":"备注2"},
{"id":3,"url":"22222","remark":""},
{"id":4,"url":"222","remark":""},
{"id":5,"url":"2222","remark":""},
{"id":6,"url":"22222是","remark":"beizhu6"}
]
