console.log(result.message); // Log the success message
console.log("Document count:", result.results); // Log the document count

Example
Suppose you have a JSON database named your_database.db and a table named users. You want to determine the total number of user records in the users table. Here's how you would use the countDoc method:
const dataname = 'your_database.db'; // Specify the name of your database
db.countDoc(dataname)
.then((result) => {
if (result.acknowledged) {
console.log(result.message); // Log the success message
console.log("Document count:", result.results); // Log the document count
} else {
console.error(result.errorMessage); // Log any error message
}
})
.catch((error) => {
console.error('An error occurred:', error); // Catch any unexpected errors
});Feel free to adapt this example to your specific use case! 😊
