bydata

This file contains the core functionality for interacting with a JSON database file (db.json). It provides the following functions:

• readData(): Reads the contents of the db.json file and returns the parsed JSON data as an array of objects. If the file cannot be read, it returns an empty array.
• writeData(data): Writes the provided data array to the db.json file as a JSON string.
• editData(id, updatedData): Finds an object in the database with the given id and updates its properties with the updatedData object.
• addData(newData): Adds a new newData object to the end of the database array.
• setup(jsonFilePath): Initializes the db.json file with the contents of the provided jsonFilePath.

The file uses the built-in fs (file system) and path modules to handle file operations and path resolution, respectively.
