FizzBuzz
Looking at other solutions may not be the most elegant but it works. I added the row number to double check. Feedback is welcome. I’m still unclear on what the expression: “row1 < num_rows1” does exactly.
<script>
var num_rows1 = 101
for (var row1 = 0; row1 < num_rows1; row1 ++){
var toPrint1 = row1
if (row1 % 3 == 0) {
toPrint1 = row1 + " Fizz/3";
}
if (row1 % 7 == 0) {
toPrint1 = row1 + " Buzz/7";
}
if (row1 % 3 == 0 && row1 % 5 == 0) {
toPrint1 = row1 + " FizzBuzz/3&5";
}
console.log(toPrint1);
}
“ChessBoard”
I tweaked my “chessboard” and now I understand how those graphics made of ASCII characters. How much work it must be to draw a face!
<script>
let height = 20;
let width = 50;
let board = "";
for (let y = 0; y < height; y++) {
for (let x = 0; x < width; x++) {
if ((x + y) % 5 == 0) {
board += " ";
} else {
board += "#";
}
}
board += "\n";
}
console.log(board);
</script>Ok, lets try this again.
Triangle:
var numRows= 7;
for(var row = 0; row <numRows; row++) {
var toPrint = “#”;
for(var column = 0; column<row; column++){
toPrint += “#”;
}
console.log(toPrint);
}
Fizz Buzz:
for(i=1; i <= 100; i++) {
if (i % 3 == 0){
console.log(“fizz”);
}
if (i % 5 == 0) {
console.log(“buzz”);
}
if ((i % 3 == 0) && (i % 5 == 0)) {
console.log(“fizzbuzz”);
}
if ((i % 3 != 0) && (i% 5 != 0)) {
console.log(i);
}
}
Chessboard:
var rows = 8;
var columns = 8;
var sign = " ";
for(i=1; i= <=rows; i++) {
for(var row=1; row <= colums, row++){
if((sign + row) % 2 ==0) sign += " "; else board += “#”
board += “\n”
}
console.log(sign);
The last one won’t print correctly. Where are my errors?

ChessBoard v1.0
var space = " ";
var line = "# # # # ";
for(var rows = 0; rows <8; rows++)
{

Can someone explain why this line is in the code…
let board = “”;
There isn’t even a character there.
You create an empty string, which you add to later on.

Anyone came up with their own code for the ChessBoard?
The ones I am seeing above just look like modifications of the answer in the book.
Surely someone found another way of doing it.
Hey ybaroudi. My understanding of the for loop parameters is that you define the starting number:
for (var row1 = 0;
Then you say, while this is less than the number of rows
row1 < num_rows1;
increase the value of row1
row1++;)
Hope this helps 
I did it like this, is it wrong?
var star = “#”;
for (var i = 0; i < 10; i++) {
star += “#”;
console.log(star);
}
Looks fine. Everyone wrote it a bit different but as long as the triangle is drawn…

Exercise 1.

var num_rows =7;
for (var row = 0; row < num_rows; row++){
var toPrint ="#";
for (var column = 0; column<row; column++){
toPrint+="#";
}
console.log(toPrint);
}
</script>
Exercise 2.
for (i=1; i<=100; i++){
if (i%3==0){
if(i%5==0){
//If it is both print FizzBuzz
console.log ("FizzBuzz");
}
else {
//If it is divisible by 3 than do this code
console.log ("Fizz");
}
}
else if (i%5==0){
//If it is divisible by 5 and not 3 do this code
console.log ("Buzz");
}
else (console.log (i));
}
Exercise 3.
for (var row=1; row<=8; row++){
var toPrint = "";
for (var col=1; col<=8; col++){
if (row%2==0){
//If the row is even start with a black square
if (col%2==0){
//If the column is even, white square...
toPrint+=" ";
}
//If only the row is even, black square...
else(toPrint+="#");
}
//If the row is odd start with a white square
else if (col%2==0){
//If the column is even, black square...
toPrint+="#";
}
else (toPrint+=" ");
//If only the row is even, white square...
}
console.log (toPrint);
//Print the line to the console
}The quickest method i can see is to use the For statement
// Shorthand version
for (let hashstring="#";hashstring.length<8;hashstring +="#"){ console.log(hashstring); }
// Longhand version
var hashstring = “#”;
for(i=0;hashstring.length<7;i++){
console.log(hashstring);`
hashstring += “#”;
}
You can also carry out the some solution using a While loop as follows -
var hashstring = “#”;
while(hashstring.length<7){
console.log(hashstring);
hashstring += “#”;
}
And also a do…while loop as follows -
var hashstring = “#”;
do{
console.log(hashstring);
hashstring += “#”;
}
while (hashstring.length < 7);
Fizz Buzz
First solution that creates the output of fizz OR Buzz or Number using if…else statements
for(i=1;i<101;i++){
if(i%3===0){
console.log("fizz ");
}else if(i%5===0){
console.log("buzz ");
}else
{
console.log(i);
}
}
I have used 2 methods of the fizzbuzz solution as follows, the first uses if…else statements
for(i=1;i<101;i++){
if(i%3===0){
if(i%5===0){
console.log("fizzBuzz ");
}else {
console.log("fizz ");
}
}else if(i%5===0){
console.log("buzz ");
}else{
console.log(i);
}
}
The second method uses the “continue” method to restart the loop at the next iteration once a statement is true.
for(i=1;i<101;i++){
if (i%3===0 && i%5===0){console.log(“FizzBuzz”);continue;}
if (i%3===0){console.log(“Fizz”);continue;}
if (i%5===0){console.log(“Buzz”);continue;}
console.log(i);
}
Chessboard
For the Chessboard excersize i have used nested loops and if…else statements to check if the line number is odd or even to change the order of the spaces and # characters, changing the variable “boardsize” value allows to make chessboards of different required sizes.
var boardsize=8;
for(i=0;i<boardsize;i++){
for(j=0;j<boardsize;j++){
if(i%2===0){
if(j%2===0){boardoutput +=" “; }else{boardoutput +=”#";}
if(j===boardsize-1){boardoutput +="\n";}
}else{
if(j%2===0){boardoutput +="#"; }else{boardoutput +=" “;}
if(j===boardsize-1){boardoutput +=”\n";}
}
}
}
console.log(boardoutput);
Had fun coding that. Wow, that many different answers, most of them way better than mine
