 // e) Describe what the expression Number(carPrice.replaceAll(",","")) is doing - what is the purpose of this expression?
+// The expression is converting the string value of carPrice, which contains a comma, into a number by first removing the comma using the replaceAll method and then converting the resulting string into a number using the Number function. This allows for mathematical operations to be performed on carPrice.
