// Write your function here:

function calculateWeight(earthWeight, planet) {
  if (!Number.isInteger(earthWeight)) {
    return("Please enter an integer for weight.");
  }
  if (typeof planet !== "string") {
    return("Please enter a string for planet.");
  }

  switch (planet) {
    case "Mercury" :
      return earthWeight * 0.378;
    case "Venus" :
      return earthWeight * 0.907;
    case "Mars" :
      return earthWeight * 0.377;
    case "Jupiter" :
      return earthWeight * 2.36;
    case "Saturn" :
      return earthWeight * 0.916;
    default :
      return("Invalid Planet Entry. Try: Mercury, Venus, Mars, Jupiter, or Saturn.");
  }
}

console.log(calculateWeight(100, "Camembert"));





// Uncomment the line below when you're ready to try out your function
// console.log(calculateWeight(100, 'Jupiter')) // Should print 236

// We encourage you to add more function calls of your own to test your code!
