Defining Data Types in Mongoose Schema

const mongoose = require("mongoose");

const userSchema = new mongoose.Schema({

  name: { type: String, required: true },

  age: { type: Number, min: 18 },

  email: { type: String, unique: true },

  isActive: { type: Boolean, default: true },

  hobbies: { type: [String] }, // Array of Strings

  createdAt: { type: Date, default: Date.now },

});

const User = mongoose.model("User", userSchema);
