Golang : Underscore or snake_case to camel case example

A quick example on how to convert underscore or snake_case statement to camel case. Pretty much similar to the previous tutorial on how to transform spinal case to pascal case.

Here you go!

 package main

 import (
 "fmt"
 "strings"
 )

 func snakeCaseToCamelCase(inputUnderScoreStr string) (camelCase string) {
 //snake_case to camelCase

 isToUpper := false

 for k, v := range inputUnderScoreStr {
 if k == 0 {
 camelCase = strings.ToUpper(string(inputUnderScoreStr[0]))
 } else {
 if isToUpper {
 camelCase += strings.ToUpper(string(v))
 isToUpper = false
 } else {
 if v == '_' {
 isToUpper = true
 } else {
 camelCase += string(v)
 }
 }
 }
 }
 return

 }

 func main() {
 snakeCase := "this_is_a_statement_with_underscore_which_is_also_known_as_Snake_Case"
 result := snakeCaseToCamelCase(snakeCase)

 fmt.Println(snakeCase)
 fmt.Println(result)
 }

Output:

this_is_a_statement_with_underscore_which_is_also_known_as_Snake_Case

ThisIsAStatementWithUnderscoreWhichIsAlsoKnownAsSnakeCase
