Lesson 23 Clearing Up the Crates visuals when re running code
Is your feature request related to a problem? Please describe. Not a bug, but a visual update for clarity. After running the correct code the crates will disappear as intended, but when rerunning the code again the pop_back() animation will play again with absent crates.
Describe the solution you'd like It's a small visual enhancement to have the crates reappear right after rerunning the code again to show that the existing crates are disappearing
Describe alternatives you've considered After clicking [Run], a line of code can make the crates reappear before the while loop begins to help show that the crates are being removed
Additional context
