 // b) Run the code and identify the line where the error is coming from - why is this error occurring? How can you fix this problem?
 
-The error is occurring on line 5 because a comma is missing between the arguments in the replaceAll function, to fix the problem,
- we need to include the "," character in the replaceAll function like this: priceAfterOneYear.replaceAll(",", "")

 // e) Describe what the expression Number(carPrice.replaceAll(",","")) is doing - what is the purpose of this expression?
-The expression "Number(carPrice.replaceAll(",", ""))" is performing two main operations:
-1. "carPrice.replaceAll(",", "")": This part of the expression removes all commas from the string representation of
-"carPrice". For example, it converts "10,000" to "10000".
-2. "Number(priceAfterOneYear.replaceAll(",", ""));": This part converts the resulting string (after removing commas) 
-into a numeric value. The purpose of this expression is to convert the string representation of a number that 
-may contain commas into an actual numeric value that can be used for mathematical calculations.
