Hy,

I was wandering about the output. You should put the printout in the listings, as the markdown kills all the leading spaces. Your result should look like this:

   #
  ##
 ###
####
Enter fullscreen mode Exit fullscreen mode

Anyway, this is also a nice case to learn some recursion:

function stair(n){
  function f(i){  
    if(i>=0){
      console.log(" ".repeat(i)+"#".repeat(n-i))
      f(i-1)
    }
  }
  f(n-1)
}
stair(4)
Enter fullscreen mode Exit fullscreen mode

If you like the freak style, you can also create a "one-liner":

const stair=(n,f)=>(f=(i)=>{console.log(" ".repeat(i)+"#".repeat(n-i));i?f(i-1):0 })(n-1)
stair(4)
Enter fullscreen mode Exit fullscreen mode

It works, try it out
