[Golang] Multiple Type In Struct

This article provides a Golang tutorial on handling JSON fields that can be either a string or a number when unmarshalling into a struct. It demonstrates using the json.Number type from the encoding/json package to avoid type mismatch errors. The article includes a code example showing how to unmarshal JSON with amount as both a string and a number, and how to convert the json.Number to float64, int64, or string. This is useful for developers dealing with flexible JSON APIs in Go.
