Garbage collection

Target C

LichenScript use both reference counting and mark-and-sweep to reclaim unused memory.

All the objects in LichenScript has a counter to count the references. When the counter go down to zero, the memory of the object will be freed.

But there a problem called cyclic references, which lead to memory leaks. So a mark-and-sweep collector is introduced to solve this problem.

⚠️

The mark-and-sweep collector is not stable yet. So it's turned off by default. It will be opened by default as soon as possible.

JavaScript has its own garbage collector. There is nothing to worry about.
