How to traverse query in mongodb?

Question

There is an existing array as follows,

const idArr = ['5950b7bfe78afb0868dc6599','5950b532b3c06f0838ed47e2','5950afcc85881f07bf454232'];
//数组每一项都作为查询的_id，遍历查询，该如何操作呢？

idArr.forEach((item,index)=>{
    db.details.find({_id:item}); //这样吗？还是。。。
});

Answer 1

The answer was found in the official documentation of mongodb

const idArr = ['5950b7bfe78afb0868dc6599','5950b532b3c06f0838ed47e2','5950afcc85881f07bf454232'];
db.details.find({_id:{$in:idArr}); //这样就可以了，一次全部查出来
