Arrow function expression stopped code from working

So I learned about arrow function expressions so I decided to change my functions for the random quote generator. The first two functions getRandomNumber and getRandomQuote work fine when I change the functions to function expressions. But the 3rd one printQuote gives me an error "Uncaught ReferenceError: printQuote is not defined at script.js:3 (anonymous) @ script.js:3"

when I change it to const printQuote = () = > { etc...

Now when the printQuote function was typed out in the original way I didnt get this problem. I know I can just move that line of code to the end but Im wondering why this became an issue after I made the change? Seems really important when I'll be developing more complex applications.

```javascript // event listener to respond to "Show another quote" button clicks // when user clicks anywhere on the button, the "printQuote" function is called document.getElementById('loadQuote').addEventListener("click", printQuote, false);

// Array of quotes for random number generator. The random number generated will be used choose an index in the array to print. var quotesArray = [ {quote: "Let them be helpless like children, because weakness is a great thing, and strength is nothing" , source: "Andrei Tarkovsky", citation: "Stalker", year: "1979"}, {quote: "The man who lies to himself and listens to his own lie comes to a point that he cannot distinguish the truth within him, or around him, and so loses all respect for himself and for others.

var quoteHTML var printedQuotesArray = []; var chosenObject

// Logs array in console. for (var prop in quotesArray) { console.log(quotesArray[prop]); }

// Random number function to length of array. Rounds down to account for 0 index. const getRandomNumber = () => { var randomNumber = Math.floor(Math.random()* quotesArray.length); return randomNumber; }

// Logs random number 20 times to check functioning of getRandomNumber function. for (var i = 0; i < 20; i += 1) { console.log (getRandomNumber()); }

// Gets random quote based off of getRandomNumer() and builds HTML quote and details to print into HTML file. const getRandomQuote = () => { var i = getRandomNumber(); return quotesArray[i]; }

// Takes whatever array is returned from getRandomQuote() function, logs quotes in console and builds string into quoteHTML to print to index.html. const printQuote = () => { chosenObject = getRandomQuote(); quoteHTML = '<p class="quote">' + chosenObject.quote + '</p>'; quoteHTML += '<p class="source">' + chosenObject.source; if (chosenObject.citation !== "") { quoteHTML += '<span class="citation">' + chosenObject.citation + '</span>'; } if (chosenObject.year !== "") { quoteHTML += '<span class="year">' + chosenObject.year + '</span></p>'; } var quoteOutputDiv = document.getElementById('quote-box'); console.log(quoteHTML); quoteOutputDiv.innerHTML = quoteHTML; } printQuote(); // Automatically prints another quote every 30 seconds. setInterval(printQuote, 30000); ```
