v8 | manually initiate the garbage collector

Question

Is there a way to manually initiate the garbage collector on Google's V8 engine? I couldn't find any reference for it. by usually GCs support this function.

Answer 1

• You can expose the v8::HEAP->CollectAllGarbage function to the global JavaScript namespace via the command flag --expose_gc. Then simply call gc();.

• You can force garbage collection from C++ via the statement:

  while(!V8::IdleNotification()) {};

Answer 2

Use V8::AdjustAmountOfExternalAllocatedMemory
