Javascript Help

I have given up here. I can't see how this would logically work. I had done it using a switch case statement, but the guy said that it didn't use nested loops . I cant use objects or any of that shit here, only conditional statements and loops.
Any help?

 

Bump.

 

Don't know JavaScript however in Java you would do :

Code:

 int numLines = 13;
        for (int i = 0; i < numLines; i++) {
            if (i == 1) {
                System.out.println("*");
            }
            if(i == 2) {
                System.out.println("**");
            }
        }

Yeah I know that code is messy and not sure if you're allowed to do that but ehh.

 

Yeah I should probably say I can read most programming languages no problem But that's not nested for loops

 

I don't want to completely do your homework for you so here's how I've done it in Python to help you understand where the nested for loop comes in (to print the right number of stars) and how you decide whether you have reached the halfway point or not since this affects how many you are printing. Doing this the right way allows you to do it for any number of rows specified.

Code:

rows = 13

half = (rows + 1) / 2

for i in range(1, rows+1):

   if i > half:
      starCount = half - (i - half)
   else:
      starCount = i
   for star in range(0, starCount):
      print '*',
   print

 

Ah I didn;t think of it like that. It makes sense now.
