PHP uses copy-on-write to manage memory. During write replication, make sure that no memory is wasted when copying values between variables. For reference calculation, make sure that the memory is returned to the operating system when the reference

Introduction to V8 garbage collection mechanismThe implementation of the V8 garbage collector is a very important reason for V8 efficiency.V8 automatically reclaims object memory that is no longer needed at run time, which is also garbage collection.

The Core Foundation framework is Apple's offering a set of concepts derived from the Foundation framework, programming interfaces for C-style APIs. While it is cumbersome to invoke this C-style API in Swift, it is sometimes very convenient to use
