How do I avoid reflection-heavy encoders in Go?

In Go, it is essential to utilize encoding techniques that minimize reliance on reflection due to performance considerations. Reflection can lead to slower execution times and increased memory usage. Instead, you can use strongly typed structures and implement your own marshaling methods to efficiently encode data.

        
        package main

        import (
            "encoding/json"
            "fmt"
        )

        type Person struct {
            Name string `json:"name"`
            Age  int    `json:"age"`
        }

        // Custom marshaling without reflection
        func customEncode(p Person) string {
            jsonData, err := json.Marshal(p)
            if err != nil {
                fmt.Println("Error encoding:", err)
                return ""
            }
            return string(jsonData)
        }

        func main() {
            person := Person{Name: "Alice", Age: 30}
            encoded := customEncode(person)
            fmt.Println("Encoded person:", encoded)
        }
