Concurrency safe file access in Go

This technical article provides a guide to building a concurrency-safe file storage system in Go. It explains how to use the sync.Mutex primitive to protect a map data structure during concurrent read and write operations, ensuring consistency between the in-memory store and a persistent JSON file. The article includes a reference implementation with code examples for initialization, reading, and writing.
