WebTail Call Optimization (TCO) • A function call is a tail call if it is the very last thing in its containing function. • The calling function has no pending work to do after a tail call (in the passive flow), so its stack frame isn't needed anymore. • Some compilers can recognize tail calls and optimize them. • Just overlay the new stack frame over the memory used for the …
