Operation like count = count + 1 is very common in programming, and there is a programming term describing such operation.
Can you find out what one-word programming term describes the operation on line 3?

Can you express the statement on line 21 so that it works for any path?
For example, "/tmp/my-project/package.json"

| // The returned value is bigger than (and may possibly equal) 1 and is less than (and may possibly equal) 100; |

What do you mean by "may possibly"? Can the expression ever evaluate to 1 and 100? Yes or No?

In the function call .replaceAll(",", ""), there's a programming term for "," and "" (the values passed into the function). Could you find out what that term is so that you can more precisely describe where the comma is missing?

Could we expect this program to work as intended for any valid penceString if we deleted .padEnd(2, "0") from the code?
In other words, do we really need .padEnd(2, "0") in this script?

I think the question is asking what we can expect the function prompt() to return in general, and not what it returned when you called the function.

| It stores different data such as, debug, error, info, log, warn, and etc. |

We don't normally refer to debug an log as data. Can you find a more appropriate term to describe them?
