Is there a way to create a pyramid number structure in JavaScript?
for (i = 1; i <= 5; i++) {
var k = ' ';
var myspace = '';
for (j = 0; j < i - 0; j++) {
k += i;
myspace += ' ';
}
console.log(myspace + k);
}
I am trying to achieve this kind of pattern:
1
2 2
3 3 3
4 4 4 4
Give this code a go:
function buildTriangle(length) {
for (var i = 0; i < length; i++) {
var result = '';
for (var j = 0; j < length - i; j++) result += ' ';
for (var k = 0; k <= i; k++) result += (i + 1) + ' ';
console.log(result);
}
}
buildTriangle(4);Check out the following solution.
var x;
var y = 10;
for (var a = 0; a <= y; a++) {
for (var b = 0; b <= a; b++) {
document.write(b + " ");
}
document.write("<br />");
