User selection in JSON?

Question

JavaScript

Guys, tell me, please, how to make a user choice in JSON. I need to select a user from an array, but the problem is that the user is in multiple conversations. How to make user selection of a specific conversation?

Answer 1

you need to have a conversation base and an array with users in it, then you need to find the conversation base by its id and then also find the user from the array.
I will make an example:

const base = [
  {
    "chatId": 1,
    "users": [
      {
        "id": 123
      }
    ]
  }
]; // типа JSON-база

// представим, что объект сообщения ВК называется message

const peer = base.filter(x => x.chatId === message.chatId)[0];
const user = peer.users.filter(x => x.id === message.senderId)[0];
console.log(user);
