My versions are longer than the answers, still I managed to get the outputs right:
1:
var a = “#”;
while(a.length < 8) {
console.log(a);
// console.log("
");
a = a + “#”;
}
2:
for (var b = 1; b < 101; b = b + 1) {
if (b % 3 == 0 && b % 5 == 0) {
console.log(“Fizzbuzz”);
}
else if (b % 3 == 0) {
console.log(“Fizz”);
}
else if (b % 5 == 0) {
console.log(“Buzz”);
}
else {
console.log(b);
}
}
3:
var size = 8;
var x = “\xa0”;
var y = “#”;
for (var row = 0; row < size; row = row + 1) {
if (row % 2) {
var str = “”;
for (var a = 0; a < size; a = a + 1) {
if (a % 2) {
str = str + x;
}
else {
str = str + y;
}
}
}
else {
var str = “”;
for (var b = 0; b < size; b = b + 1)
if (b % 2) {
str = str + y;
}
else {
str = str + x;
}
}
console.log(str)

javedkhalil,
I am intrigued with your coding for FizzBuzz considering the number 15 in the initial set up since 3 and 5 come together at number 15 (3 x 5 =15), and is less than 100. And also, 30, 45, 60, 75, 90, and not past 100 wherein the loop would stop since 105 is greater than 100. Since these numbers were not presented in the initial discussion of the assignment, I wondered if it would be confusing to follow. Using the information given was clearer for me. It took me awhile because I had noticed % 15 in more than 1 answer by others. I haven’t worked with it yet. Does the code work when you reduce 100 to 10? (both 3 and 5 are < 10 and meet the criteria of <= 100. It might work as well? I look forward to trying your FizzBuzz Loop for fun. It is fascinating how this coding works. Thank you,
Lorraine

Now it should it be correct. Didn’t know you can part them with the three ` thanks for that @Malik
I wrote my code this way, and it differs from the textbook answer even thou the results are the same. Is there anything wrong with this?
for (a=1; a <=100; a++){
if(a%3 ==0 && a%5 !==0){
console.log("Fizz");
}
else if(a%5 ==0 && a%3 !==0){
console.log("Buzz");
}
else if(a%3==0 && a%5==0){
console.log("FizzBuzz");
}
else console.log(a);
}
/* Textbook solution
for (let n = 1; n <= 100; n++) {
let output = "";
if (n % 3 == 0) output += "Fizz";
if (n % 5 == 0) output += "Buzz";
console.log(output || n);
}

This answer is fine as well.
Happy Learning! 
Great Exercises!
Please let me know what you think about my approach.
Don’t see anyone else using this approach but it works.
Here is my code:

var toPrint = "#";
for(column = 0; column<row; column++) {
toPrint += "#";
}
console.log(toPrint);
}
//FIZZBUZZ
for(let counter = 1; counter <= 100; counter++){
if(counter % 5 === 0 && counter % 3 ===0){
console.log("fizzbuzz");
}
if(counter % 3 === 0 && counter % 5 !== 0){
console.log("fizz");
}
if(counter % 5 === 0 && counter % 3 !== 0){
console.log("buzz");
}
else if(counter % 5 !== 0 && counter % 3 !== 0){
console.log(counter);
}
}
//chessboard
var rows = 8;
//Change var rows to change row length chessboard
for(row = 0; row < rows; row++){

//Change First number after repeat to change column length chessboard(part1/2)
console.log(multiStr);
}
else if(row % 2 !== 0){
var multiStrTwo = " #".repeat(8/2);
//Change First number after repeat to change column length chessboard(part2/2)
console.log(multiStrTwo);
}
}

FizzBuzz - I did this two ways - I think the second way is more efficient since it doesn’t involve overwriting a variable.
1.
for(i=1;i<=100;i++){
toPrint = i;
if(toPrint%3 == 0 && toPrint%5 ==0){
toPrint = "FizzBuzz";
}
else if(toPrint%3 ==0){
toPrint = "Fizz";
}
else if(toPrint%5 == 0){
toPrint = "Buzz";
}
console.log(toPrint);
}
for(i=1;i<=100;i++){
if(i%3 == 0 && i%5 ==0){
console.log("FizzBuzz");
}
else if(i%3 ==0){
console.log("Fizz");
}
else if(i%5 == 0){
console.log("Buzz");
}
else console.log(i);
}
Chessboard
var grid_size = 8;
var toPrint = "";
var space = true;
for(cols = 0; cols<grid_size; cols++ ) {
toPrint += "# ";
}
for(rows=0; rows<grid_size; rows++ ) {
if(space == true){
console.log(" " + toPrint);
space = false;

else{

space = true;

// this one only works for even numbers. I hadda look at the solution to find the answer for code that works for even && odd numbers. This is as far as I got before peekin @ the answer:

I like ur approach Gos

function makeLine(length){
var line = “”;
for (var j = 1; j <= length; j++){
line += "# ";
}
return line + “\n”;
}
function buildTriangle(x){
var triangle = ‘’;
for (t = 1; t <= x; t++){
triangle += makeLine(t);
}
return triangle;
}
console.log(buildTriangle(7));
FizzBuzz
(I did a bit extra and added some HTML and a style sheet)
function FizzBuzzA(value1, value2){
let returnValue = “”;
for(let i = 1;i<=100;i++){
if(i%value1==0 && i%value2==0){
returnValue += 'FizzBuzz ';
}
else if (i%value1 == 0){
returnValue += 'Fizz ';
}
else if (i%value2 == 0){
returnValue += 'Buzz ';
}
else{
returnValue += i + ’ ';
}
}
return returnValue;
}
