javascript - 从数组组中删除多个对象

Question

我想将整个对象拼接到数组“Docs > Exam”中，其中包含“Pass”:“NO” 我已经尝试过了

 var docs = [
               {"Id":1,"Name":"First","Exam":[{"Pass":"No"},{"Sub":"T1"}]},
               {"Id":2,"Name":"Second","Exam":[{"Pass":"Yes"},{"Sub":"T2"}]},
               {"Id":3,"Name":"Third","Exam":[{"Pass":"No"},{"Sub":"T3"}]}
               ];

for (var i = docs.length - 1; i >= 0; i--) {
     for (var j = docs[i].Exam.length - 1; j >= 0; j--) {
             if (docs[i].Exam[j].Pass == 'No') {
                 docs.splice(docs[i],1);
             }
        }
    }
    
console.log(docs);

我只需要包含此对象的文档

{"Id":2,"Name":"Second","Exam":[{"Pass":"Yes"},{"Sub":"T2"}

使用 filter 非常容易和 some :

docs = docs.filter(doc => doc.Exam.some(exam => exam.Pass === 'Yes'))
