// Predict and explain first...

// Predict the output of the following code:
/* The last digit of 42 is 2
   The last digit of 105 is 5
   The last digit of 806 is 6
*/
const num = 103;

function getLastDigit(num) {
  return num.toString().slice(-1);
}

console.log(`The last digit of 42 is ${getLastDigit(42)}`);
console.log(`The last digit of 105 is ${getLastDigit(105)}`);
console.log(`The last digit of 806 is ${getLastDigit(806)}`);

// Now run the code and compare the output to your prediction
// =============> write the output here
/*
The last digit of 42 is 3
The last digit of 105 is 3
The last digit of 806 is 3
*/
// Explain why the output is the way it is
// =============> I just realized now that the function getLastDigit is just always just returning the last digit of cons num

// Finally, correct the code to fix the problem
// =============> write your new code here
/*
function getLastDigit(num) {
  return num.toString().slice(-1);
}

console.log(`The last digit of 42 is ${getLastDigit(42)}`);
console.log(`The last digit of 105 is ${getLastDigit(105)}`);
console.log(`The last digit of 806 is ${getLastDigit(806)}`);
