console.log(str5)This particular solution caught my attention because it utilizes just one for loop to achieve the desired outcome.
let pattern = '';
let size = 6;
let spaces = (size - 1);
for(let i = 1; i <= size; i++)
{
pattern = pattern.trim();
pattern = ' '.repeat(spaces) + pattern + (i > 1 ? ' ' : '') + '*';
console.log(pattern);
spaces--;
}
Expected Result:

for (let count = 7; count >= 1; count--) {
let string = "";
for (let index = count; index <= 7; index++) {

}
console.log(string);
}
// This is just an example
// Feel free to try this out with any string and without using a function. Here is a straightforward solution to the problem:
for(let x = 1; x <= 5; x++) {
for(let y = 1; y<= x; y++) {
document.write("*");
}
document.write("<br/>");
}
When running the following code snippet, a pattern of asterisks will be displayed on the screen based on the loop:
for (let i = 1; i <= 5; i++) {
for (let j = 1; j <= i; j++) {
document.write('*');
}
document.write('<br />');
}It seems that the desired pattern to be printed is a stair pattern, not a star pattern based on your code.
The main issue you are facing is due to the fact that the console.log function prints each value on a new line.
for (var i = 5; i >= 1; i--) {
var str = "";
for (var j = i; j >= 1; j--) str += j;
console.log(str);
}

Give it a shot
**The Pyramid will be facing downwards as shown below: **
4 3 2 1
3 2 1
2 1

function stars(n){
var str = '';
for(var i=n; i>=1; i--){
for(var k=n; k>=i; k--){
str += "\t";
}
for(var j=i; j>=1; j--){
str += j+"\t\t";
}
console.log(str);
str = "";
}
}
stars(3);
The Pyramid will be facing upwards as shown below :
*
* *
* * *
function stars(n){
var str = '';
for(var i=1; i<=n; i++){
for(var k=1; k<=n-i; k++){
str += "\t";
}
for(var j=1; j<=i; j++){
str += "*\t\t";
}
console.log(str);
str = "";
}
}
stars(3);
function buildPyramid(height) {
for(let level = 1; level <= height; level++) {
let spaces = ' '.repeat(height - level);
let blocks = '*'.repeat(level * 2 - 1);
console.log(spaces + blocks + spaces);
}
}
buildPyramid(5);
Each time the log function is called, the output will go to a new line. In Chrome, if the output is the same, it will just increment a count (not sure about other browsers). The goal is to gather the number of stars per line and then display that after the inner loop has finished.
for (var i = 5; i >= 1; i--) {
var ouput = "";
for (var j = i; j >= 1; j--) {
ouput += "*"
}
console.log(ouput);
}Give this a shot and see if it does the trick:
