How do you define schemas and models with Mongoose? const mongoose = require('mongoose'); const userSchema = new mongoose.Schema({ name: { type: String, required: true }, email: { type: String, required: true, unique: true },

ge: Number,

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

});

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

// Usage example

sync function createUser() {

const user = new User({ name: 'Alice', email: 'alice@example.com',

ge: 25 });

wait user.save();

console.log('User saved');

}
