Sprint-1/1-key-exercises/1-count.js

 // Describe what line 3 is doing, in particular focus on what = is doing
+
+/*
+Line 3 is re-assigning the variable "count" with a new value that increases the previous value by 1


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?

+// Line 5-

+// SyntaxError: missing ) after argument list


Can you give a more specific reason why the error occurs? (You didn't fix the error by adding a ). )

Sprint-1/3-mandatory-interpret/3-to-pounds.js

+   2. const penceStringWithoutTrailingP = This stores the substring of penceString by extracting all characters except the final p. It takes the substring from index 0 up to (but not including) the last character p, so "399p" becomes "399". This removes the unit symbol so only the numeric portion remains.
+   3. const paddedPenceNumberString= This stores the value of penceStringWithoutTrailingP, padded to a total length of 3 characters by adding leading zeros where necessary. This guarantees there are always enough digits to separate pounds and pence correctly.
+   4. const pounds= Stores the substring of paddedPenceNumberString from index 0 to the last 2 index. These leading digits represent the pound portion of the amount.
+   5. const pence=  Extracts the final two digits of the padded string to represent the pence portion. padEnd(2, "0") ensures that the pence value always contains exactly two digits.


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?

-What is the return value of `prompt`?
+
+What effect does calling the `prompt` function have?A modal appears with the "What is your name?" with an input field to enter your name. The input is then stored in the variable myName
+What is the return value of `prompt`? My name stored in the variable myName


I think the question is asking what return value can the caller expect from the function prompt()
