拼接后更新JSON文件

Question

I have a JSON file called database.json. I manage to update, add and manipulate it but couldn't manage to delete from it in a safe way. Here is the summary of my problem in code;

database.json;

{
  "faqs": {
    "questions": {
      "1": "Question is deleted",
      "2": "b",
      "3": "c"
    },
    "answers": {
      "1": "aa",
      "2": "bb",
      "3": "cc"
    }
  }
  ...
}

const fs = require('fs');
const ReadDatabase = fs.readFileSync('database.json');
const ReadData = JSON.parse(ReadDatabase);
let questionsObjects = ReadData.faqs.questions;
let questionObjectKeys = Object.keys(ReadData.faqs.questions)

let removed = questionObjectKeys.splice(0,1); //This
let editedDataBase = JSON.stringify(ReadData, null, 2);
fs.writeFileSync('database.json', editedDataBase);

Where I commented This, removes is and stores as removed, I can't figure out, how am I gonna update it that onto the file and just delete the key-value pair and rest will be there.

Answer 1

delete questionsObjects["1"];

The answer was simple just adding this instead of splice works perfect and it updates the database as well. It is I guess all about asking the right question and the way I asked wasn't answered because it's in wrong format.

Where I find the solution after a long search before and some search after this post
