// Subtract a number from an existing value
db.extract('UserNumber', 2);

// Delete a specific key
db.delete('UserAvatar');

// Push a value to an array
db.push('UserList', 'John Doe');

// Check if a key exists
console.log(db.has('UserList')); // true or false

// Fetch a specific value
console.log(db.fetch('UserList'));

// Fetch all data
