# Learn Introductory JavaScript by Building a Pyramid Generator - Step 70

### Tell us what’s happening:

Can anybody explain this process in detail
I want to know the detailed explanation of the below questions

In my POV the parameter “rowCount” carries the value of Count which was declared in the for loop
The value of count is the default value “8”
If the rowCount is 8,
How " ".repeat(rowCount - rowNumber) is able to properly divide the spaces??
Can somebody please explain the process with an example of rownumber or i = 1 ??

question 2
Also What change is this statement able to make??
return " ".repeat(rowCount - rowNumber) + character.repeat(rowNumber) + " ".repeat(rowCount - rowNumber);
}

In the above function,
with this line // character.repeat(rowNumber)
the output is

``````               #
##
###
####
#####
######
``````

How are the spaces adjusted just by updating the below line??
character.repeat(2 * rowNumber - 1)
Even it is gonna return the same output?

``````const character = "#";
const count = 8;
const rows = [];

// User Editable Region

return " ".repeat(rowCount - rowNumber) + character.repeat(rowNumber) + " ".repeat(rowCount - rowNumber);
}

// User Editable Region

for (let i = 0; i < count; i = i + 1) {
}

let result = ""

for (const row of rows) {
result = result + "\n" + row;
}

console.log(result);
``````

You’re correct `rowCount` takes the value assigned to `count`

Can you see where `rowNumber` gets it’s value?

I think its the argument provided to the padRow function in the for loop
Which is i + 1

for (let i = 1; i < count; i++) {
}

Correct, so you can see that `i` increments and `rowNumber` changes and this affects how many spaces and `#` are printed?

I know that when i increments, the rowNumber changes
But how the process of subtraction works?
For suppose if we consider i = 1
Then " ".repeat(rowCount - rowNumber)
" ".repeat(8 - 1)

I’m sorry I got the clarity when I’m typing the above question
I didn’t realize that it is gonna leave the i spaces on each side
I actually took a pen,paper & confirmed that
Thank you for making me dwelve into the deep
Thank you!

I think it’s great that you took the time to follow the logic through and really understand it. It can get very abstract, especially when you are following a guide like this.

If you are designing the program yourself I think it gets much easier to follow because you are really “inside” the problem. It’s more difficult to understand logic that’s already written (which is why it’s important to leave comments in your code for other people to follow)
