Why Is Garbage Collection So Important? [closed]

Question

I don't understand garbage collection so good, then I want to know, why it's so important to a language and to the developer?

Answer 1

Many other answers have stated that garbage collection can help to prevent memory leaks but, surprisingly, nobody seems to have mentioned the most important benefit that GC facilitates memory safety. This means that most garbage collected environments completely abstract away the notion of memory locations (i.e. raw pointers) and, consequently, eliminate a major class of bugs.

For example, a common mistake with manual memory management is to accidentally free a value slightly too early and continue to use the memory at that location after it has been freed. This can be extremely difficult to debug because freed memory might not be reallocated and, consequently, seemingly valid operations can be performed on the freed memory that can only fail sporadically with corruption or memory access violations or segmentation faults later in the program's execution, often with no direct link back to the offending code. This class of bugs simply do not exist in most garbage collected environments.
