Schema type options

let book2 = new Book({
  title: "Marvel Comics",
  author: "stan lee",
  price: 499,
  category: "comics",
})
  .save()
  .then((res) => {
    console.log(res);
  })
  .catch((err) => {
    console.log(err);
  });



NOW THE CONDITIONS:

 title: {
    type: String,
    required: true,
    maxlength: 5,
  },


  discount: {
    type:Number,
    default: 0,
  },

HERE WE DIDN'T DEFINE DISCOUNT ,BUT IN THE OUTPUT WE CAN SEE IT, AS IT IS DEFAULT




category: {
    type:String,
    enum: ["fiction", "non-fiction"],
  },

THERE ARE MANY MORE SCHEMA TYPES ,REFER:https://mongoosejs.com/docs/schematypes.html
