i want to remove ojbject key = "a" , "id" and its value

My current code:

  Thank you. It worked for normal json.

  How can i remove key For nested json, like remove answers:

  Thank you

  var quizContent = [
    {
      "question": "Why is the sky blue?",
      "answers": [
        { "answer": "Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere." },
        { "answer": "Idk dude" },
        { "answer": "google.com" },
        { "answer": "It just is." }
      ]
    },
    {
      "question": "Why did the chicken cross the road?",
      "answers": [
        { "answer": "To get to the other side." },
        { "answer": "Obama amiriteeee" },
        { "answer": "To escape genocide. "},
        { "answer": "To find itself." }
      ]
    }
  ]

  Same way:  But because var quizContent is an array and the json is element 0 in the array you must get element 0 first

  key = "answers";
  delete quizContent[0][key];
  JSON.stringify(quizContent)
