Solution 1 (Click to Show/Hide)

// the global variable
var fixedValue = 4;

// Add your code below this line
function incrementer(value) {
  return value + 1;

  // Add your code above this line
}

var newValue = incrementer(fixedValue); // Should equal 5
console.log(fixedValue); // Should print 4

Code Explanation

This code will provide the same result as the last challenge, only this time we will pass the fixedValue into the function as a parameter.
