    Creating Staircase Pattern In Javascript

    In the Below function we have first created a function staircase which takes n : number of rows of the staircase as parameter to it. Then the function print the staircase with n rows. In the function we have one outer loop and two inner loops. 

code:

function staircase(n){
    for(let  i = 0; i < n; i++){
        let str = ''
        let str1 = ''
        for(let j = 0; j < n - i - 1; j++){
            str += " "
        }
        for(let k = 0; k <= i; k++){
            str += "#"
        }
        console.log(str+str1)   
    }
}
staircase(5)
 

Output:
