Hi @NicoG,
The FizzBuzz exercise is spot on! However, chessBoard exercise seems to have a lot of issues. These issues include spelling mistakes, syntax error, missing brackets etc.
Please could you redo the exercise, if you’re stuck you can take inspiration from the answers above.
Hope this helps. Please feel free to reach out if there’s anything else you need.
Happy Learning!

Hi @George,
Amazing answer George! However, the Triangle #'s exercise does not yield the right answer. Could you try again, if there’s any help you require please feel free to reach out.
Happy Learning!
Hi @Malik,
Thank you for pointing out, fixed it now:
displayTriangle.length < row
instead of toDisplay.length < row
Greetings @NLUGNER,
Seems like there is an issue in this exercise answer. Please could you redo it. If there are any doubts or concerns, please feel free to reach out.
Excellent @George! 
Happy Learning! 
let size = 8;
let board = "";
for (let y = 0; y < size; y++) {
for (let x = 0; x < size; x++) {

board += "";
} else {
board += "#";
}
}
board += "\n";
}
console.log(board);
Hi @hminott, This exercise answer seems to not give the right answer. Please try again. If you have any doubts or concerns, please feel free to reach out.
I did struggle with these exercises and being honest, I resisted the temptation to peek at the answers until I looked at the clock and 8 hours had gone by! Fortunately, most of my attempts failed due to a missing bracket or semicolon but my logic and choice of commands was good. Mainly syntax mistakes.
I realized besides learning what each function does, it’s essential to understand the bindings that are part of the language standard because they are hidden, not included with a simple explanation of what a particular function does.
Gonna keep practicing!
I really struggled with this exercise. I re-read several parts of the book and looked at various sites after attempting these many times. I am still not confident in these exercises so i am going to go back over the material before proceeding.
Triangle
var numRows = 7;
for(let row = 0; row < numRows; row++){
var printS = ("#");
for(let column = 0; column < row; column++){
printS += "#";
}
console.log(printS);
}
FizzBuzz
for (number = 1; number<100; number++){
if (number % 15 == 0) console.log(“fizzbuzz”);
else if (number % 3 == 0 ) console.log(“Fizz”);
else if (number % 5 == 0) console.log(“Buzz”);
else console.log(number);
}
Chess
let size = prompt("Enter size of the Chessboard: ");
let chess = “”;
for (row = 0; row < size; row++){
for (column = 0; column < size; column++){
if (column % 2 == 0 && row % 2 == 0){
chess += " ";
}
else if (column % 2 == 0 && row % 2 == 1){
chess += "#";
}
else if (column % 2 == 1 && row % 2 == 1){
chess += " ";
}
else {
chess += "#";
}
}
chess += "\n";
}
console.log(chess);Hi @Malik thanks for letting me know. Is this it? if not then can you help me to figure it out please 
? Thanks again.
let size = 8;
let board = “”;
for (let y = 0; y < size; y++) {
for (let x = 0; x < size; x++) {
if ((x + y) % 2 == 0) {
board += " ";
} else {
board += “#”;
}
}
board += “\n”;
}
console.log(board);
Hey everyone! I completed the two exercises. Took some time and YouTube lol. But in the end I completed them and understand things a lot better. I am really enjoying the class.
Thanks Mate! Will have a look and go through the exercise. I appreciate your comments
Looping a triangle
for (let line = “#”; line.length < 8; line += “#”)
console.log(line);
Fizz Buzz
for (let n = 1; n <= 100; n++) {
let output = “”;
if (n % 3 == 0) output += “Fizz”;
if (n % 5 == 0) output += “Buzz”;
if (n % 3 && 5 == 0) output += “FizzBuzz”;
console.log(output || n);
}
Chessboard
let size = 8;
let board = “”;
for (let y = 0; y < size; y++) {
for (let x = 0; x < size; x++) {
if ((x + y) % 2 == 0) {
board += " ";
} else {
board += “#”;
}
}
board += “\n”;

console.log(print);
