With tail recursion, the recursive call is the last thing the method does, so there is nothing left to execute within the current function. There are automatic optimizations that help alleviate this (“tail calls optimizations”), but they are not yet supported everywhere and work only in simple cases. While it is certainly a clever joke about recursion, we can truly understand it by using it. Which means if all of my recursion is done with proper tail calls, then I can do arbitrarily deep recursion with 0 of 1 memory usage, constant memory usage.
