Re: [v8-users] calling Javascript function from C++,

WebMar 11, 2024 · Function references are necessary to compile languages like C/C++ that have function pointers. In a native implementation of C/C++, a function pointer is represented by the raw address of the function's code in the process's virtual address space and so, for the safety reasons mentioned above, cannot be stored directly in linear … WebThe short answer is to keep the number of C++ -> JS transitions to a minimum. If you look at the call stack in a debugger, you'll see why it's so much slower: V8 has to insert a couple of adapter frames that convert between the JS and C++ calling conventions.
