To print an Hourglass Pattern in JavaScript, we use nested loops. The outer loop controls the rows and the inner loops control the spaces and stars (*) to form the pattern.
In this example,
printHourglass
that takes the desired number of rows n
as a parameter.for
loops, where the outer loop runs from n
to 1 and the inner loops control the spaces and stars in each row.function printHourglass(n) {
for (let i = n; i >= 1; i--) {
let spaces = ' '.repeat(n - i);
let stars = '*'.repeat(2 * i - 1);
console.log(spaces + stars);
}
for (let i = 2; i <= n; i++) {
let spaces = ' '.repeat(n - i);
let stars = '*'.repeat(2 * i - 1);
console.log(spaces + stars);
}
}
// Example usage
printHourglass(5);
