CRUD sencillo

Vamos a hacer un CRUD para la siguiente ‘base de datos’

{
  "notes": [
    {
      "id": 1,
      "content": "HTML is easy",
      "date": "2023-01-03T10:30:11.414Z",
      "important": false
    },
    {
      "id": 2,
      "content": "Browser can execute only JavaScript",
      "date": "2019-05-30T18:39:34.091Z",
      "important": false
    },
    {
      "id": 3,
      "content": "GET and POST are the most important methods of HTTP protocol",
      "date": "2023-01-09T09:29:26.131Z",
      "important": true
    },
    {
      "content": "Cchuetes",
      "date": "2022-12-18T20:25:10.598Z",
      "important": true,
      "id": 4
    },
    {
      "id": 5,
      "content": "Comprar pan",
      "date": "2023-01-09T08:46:37.794Z",
      "important": false
    },
    {
      "content": "Nueva nota",
      "date": "2023-01-09T09:29:21.122Z",
      "important": false,
      "id": 6
    }
  ]
}

De momento solo gestionamos el contenido. La fecha la ponemos automáticamente y si es importante o no lo dejamos de lado, ponemos siempre ‘false’.
