Using JSON in Go: A guide with examples

Golang, or Go, is a statically typed, compiled programming language known for its C-like syntax and minimal grammar, making it a popular choice for building high-performance software systems, especially those requiring concurrency. The language is widely used for developing developer tools, cloud computing applications, CLI programs, and both desktop and web applications. A common task in Go involves working with JSON content, where developers often need to read JSON files to populate Go objects or convert Go objects to JSON files. Go’s standard library offers the encoding/json package, which provides functions for marshaling (converting Go objects to JSON) and unmarshaling (converting JSON to Go objects), along with features to customize the process such as renaming JSON fields, generating pretty-printed JSON, and handling complex data structures. This package allows developers to effectively manage JSON data by offering tools for both simple and complex encoding and decoding tasks, including custom marshaling and unmarshaling for specific use cases.
