Minimal VI: Ternary Operator

In the Code tab you will find code that is missing a single character in order to pass the tests. However, your goal is to submit a function as minimalist as possible. Use the tips in the tips section below.

Write a function that returns the strings:

• "both" if both given booleans a and b are true.
• "first" if only a is true.
• "second" if only b is true .
• "neither" if both a and b are false.

Tips

If-else statements can be written as a oneliner using Javascript's ternary operator.

For example, the code:

function startswith(name) {
  if ("AEIOU".includes(name[0])) {
    return "vowel"
  } else {
    return "consonant"
  }
}

Can be simplified to:

function startswith(name) {
  return "AEIOU".includes(name[0]) ? "vowel" : "consonant"
}

Bonus

You can concatenate as many ternary operators as you want. However, concatenating too many can diminish the readability of your code.

x > 50 ? "majority" : x < 50 ? "minority" : "draw"
