Ruby is a programming language. Everything is clear here. In the code of this language, you may encounter the term - ZOMBIE. What does it mean in the context of Ruby code? ZOMBIE is a term used in the context of memory management to describe an object that has already been marked for destruction, but its finalizer has not yet been executed. This means that the object is already "dead" (i.e., its memory can be freed), but it still has some "viability" since the finalizer may perform additional actions before the object is completely destroyed. Finalizer is a special method in many programming languages that is automatically called before an object is destroyed by the garbage collector (Garbage Collector). The method is usually used to perform necessary cleanup operations, such as releasing resources that the object used during its lifetime.

So, a Zombie is an object that has been marked for destruction, but we are still waiting for the finalizer to clean up the memory before the object is finally destroyed.
