/* ----------------------------------------------------------------------------------------

    Create a function which answers the question "Are you playing banjo?".
    If your name starts with the letter "R" or lower case "r", you are playing banjo!

    The function takes a name as its only argument, and returns one of the following
    strings:

    name + " plays banjo" 
    name + " does not play banjo"
    Names given are always valid strings.

---------------------------------------------------------------------------------------- */

/*
    String.prototype.toLowerCase():  returns this string converted to lower case
*/

function areYouPlayingBanjo(name) {
  return `${name} ${name[0].toLowerCase() === "r" ? "plays banjo" :  "does not play banjo" }`
}
