I want to remove the very last character of a string, but before I do so I want to check if the last character is a \"+\". How can this be done?

Based on the answer of @KarthikGR the following example was added:

https://play.golang.org/p/ekDeT02ZXoq

package main

import (
    "fmt"
    "strings"
)

func main() {
    fmt.Println(strings.TrimSuffix("Foo++", "+"))
}

returns:

Foo+
