Dynamo DB-更新/删除

Question

How to do I do when I want to remove one Json object from the below example?

{ Name : "abc",
  EMail : "abc@gmail.com"
  Fruits : [{
    Name : "name",
    family: "Z"
},
{
    Name : "name",
    family: "A"
},
{
    Name : "name",
    family: "B"
},
{
    Name : "name",
    family: "C"
}
]
}

From the above example if I wanted to remove { Name : "name", family: "C" } . I know that family = C and it is unique.

How do I achieve this in Aws DynamoDB using JavaScript?

 var data = { "Name" : "abc", "EMail" : "abc@gmail.com", "Fruits" : [{ "Name" : "name", "family": "Z" }, { "Name" : "name", "family": "A" }, { "Name" : "name", "family": "B" }, { "Name" : "name", "family": "C" } ] } data.Fruits = data.Fruits.filter(val => ((val.Name == "name" && val.family != "C") || (val.Name != "name" && val.family == "C"))); console.log(data);
