You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: util.go
    path of file: ./repos/k6/vendor/github.com/jhump/protoreflect/desc/internal
    
    the code of the file until where you have to start completion: package internal

import (
	"math"
	"unicode"
	"unicode/utf8"
)

const (
	// MaxNormalTag is the maximum allowed tag number for a field in a normal message.
	MaxNormalTag = 536870911 // 2^29 - 1

	// MaxMessageSetTag is the maximum allow
    
func JsonName(name string) string {
	var js []rune
	nextUpper := false
	for _, r := range name {
		if r == '_' {
			nextUpper = true
			continue
		}
		if nextUpper {
			nextUpper = false
			js = append(js, unicode.ToUpper(r))
		} else {
			js = append(js, r)
		}
	}
	return string(js)
}
