A memory leak can also occur when an object is stored in memory but cannot be accessed by running code.
Why are memory leaks bad?
A memory leak slows down your computer’s performance by reducing the amount of memory available. Eventually, in the worst case, too much available memory can be allocated and all or part of the system or device stops working properly, the application crashes, or the system slows down tremendously due to thrashing.
