Print star tower in JavaScript using For Loop

for (let i = 1; i <= 6; i++) {

    let str = "";

    for (let j = 0; j < i; j++) {

        str += "*";

    }

    console.log(str);

}

We can use two times For Loop to print star tower because first loop print number 1 to 6

and second loop for print star.

// Result

This result is showed in the console of any user friendly browser like as Chrome.
