Problems

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.

Solution:

function areYouPlayingBanjo(name) {

// Implement me

return name + (name[0].toLowerCase() === ‘r’ ? ” plays ” : ” does not play “) + “banjo”;

}

Result:

Test.assertEquals(areYouPlayingBanjo(“Martin”), “Martin does not play banjo”);
Test.assertEquals(areYouPlayingBanjo(“Rikke”), “Rikke plays banjo”);
