Experimenting with simple algorithms brought me to this code. I'm curious if anyone has a more concise version in JavaScript for displaying a pyramid:
const max= 30;
let row = 1;
for (let i = 1; i < max; i += 2) {
console.log(' '.repeat(max / 2 - row) + '*'.repeat(i))
row++;
}
Is this the code you were looking for?
let s = '*'
for(let p=15;p--;)
{
console.log( ' '.repeat(p) + s)
s += '**'
}.as-console-wrapper { max-height: 100% !important; top: 0; }Here is a solution using the map function:
function createPyramid(height) {
return Array(height).fill('*')
.map((current, index) =>
' '.repeat(height - index) +
current.repeat(index).split('').join(' ') +
' '.repeat(height - index))
.join('\n');
}
console.log(createPyramid(30));
If you're looking for a more concise method, try using a while loop.
I found this solution particularly useful from reading the response by Mister Jojo.
let s = '*',
p = 15;
while (p--) {
console.log(' '.repeat(p) + s)
s += '**';
}.as-console-wrapper { max-height: 100% !important; top: 0; }printPattern(Array.from({length:15},(_,i)=>"*".repeat(i*2+1).padStart(15+i)).join`\n`);In Safari, the text of the button is not showing up properly. I am able to retrieve the text using jQuery in the console though. However, there seems to be an issue with recognizing the click event. <div class="btn-group btn-group-lg"> <button ...
