Sometimes the buggy code is not worth salvaging and should be deleted entirely. Reasons you might do this:

Illustration of an uneasy-looking stick figure with curly hair. - it uses a confusing library / tool

Illustration of the same person, now smiling. - you have a better idea for how to implement it

person (thinking): I bet I could avoid all these problems if I took X approach instead…
