• Try validating the user input before testing:
  • inputValue value missing: "Please enter a Character Class";

app.js

// Accept command line input
const inputValue = process.argv[2];

// Define data array
const characterClasses = [
  'fighter',
  'wizard',
  'rogue',
  'barbarian',
  'bard'
]

// Test if the entered string matches a value in characterClasses
if (characterClasses.includes(inputValue)) {
  console.log(`"${inputValue}" is a valid Character Class!`);
} else {
  console.log(`"${inputValue}" is NOT a valid Character Class! Please enter another Character Class.`);
}
