var car = "Honda Civic";

showCar();

var showCar = function(){
    console.log(car);
};

// Because of hoisting the function expression is hoisted prior to the assignment of the function expression.  Thus the call of the showCar(); breaks .

codeangler

var car = "Honda Civic";

showCar();

//  By making it a function declaration scope & hoisting are not an issue
function showCar(){
    console.log(car);
}

codeangler

var food = "pizza";

function getFood(){
  console.log(food);  //what does this line alert?
  
  // Assigning var food is hoisted w/n function w/o assignment and first console.log returns undefined.  Then var food is assigned saugages and returns "sausages"
  var food = "sausages";
  console.log(food);  // what does this line alert?
}

// 7. Write a JavaScript function that accepts a string as a parameter and counts the number of vowels within the string. Go to the editor
// Note : As the letter 'y' can be regarded as both a vowel and a consonant, we do not count 'y' as vowel here. 
// Example string : 'The quick brown fox' 
// Expected Output : 5
