+
+//ANSWER:
+
+// Line 3 is reassigning the value of count. This is because we are using "let" and not "const" which allows us to reassign values.  The value of count is being evaluated first (count + 1), which sums up to (0 + 1 = 1) and then it is updated using the assignment operator (=), which takes the result and stores it back into the count variable.
