Get string length from user input

I want to get the string length, here my code:

package main

import (
    "bufio"
    "fmt"
    "os"
    "strconv"
)

func main() {
    reader := bufio.NewReader(os.Stdin)
    fmt.Print("Text to send: ")
    text, _ := reader.ReadString('\n')
    fmt.Print(strconv.Itoa(len(text)))

}

For input: aaa

The output is 5 but should be 3.

I know I can just subtract -2 from the result but I want "cleaner" way

You need to remove whitespaces from your input:

import (
    "fmt"
    "strings"
)

func main() {
     reader := bufio.NewReader(os.Stdin)
     fmt.Print("Text to send: ")
     text, _ := reader.ReadString('\n')
     newText := strings.TrimSpace(text)
     fmt.Print(strconv.Itoa(len(newText)))    
}
