How to print Pyramid Pattern in JavaScript ?

Answer

To print a pyramid pattern in JavaScript, you can use nested loops where the outer loop controls the rows and the inner loops control the spaces and stars printed in each row.

✐ Examples

1 Pyramid Pattern with Asterisks (*)

In this example,

We define a variable n to represent the number of rows in the pyramid.
We use nested loops where the outer loop controls the rows and the inner loops control the spaces and stars printed in each row.
Inside the inner loops, we use conditions to determine whether to print a space or a star (*) based on the pyramid pattern.
After each row, we use console.log() to move to the next line.

JavaScript Program

function printPyramid(n) {
    for (let i = 1; i <= n; i++) {
        let str = ' '.repeat(n - i);
        str += '*'.repeat(2 * i - 1);
        console.log(str);
    }
}

printPyramid(5);
