📚 Book CRUD – Golang

This project is a simple application that facilitates CRUD operations (Create, Read, Update, Delete) for book data using the Go (Golang) programming language. It uses a JSON file for data storage, making it a great resource for learning backend development without the complexity of setting up a database.
