Elixir and BEAM SPOOKY
| elixir
So startled…
Server processes in Elixir are long-running processes that handle messages from other BEAM processes. They use a nifty tail recursion feature to run indefinitely. Functions that call a function as the last thing they do are called tail function calls.
Erlang treats tail function calls in a special manner. Normally a
function call would result in allocating another stack (
stack level too deep lol), but Erlang perform a
tail call optimization that prevents this. Instead, a “jump statement”
happens and no additional memory allocation occurs.
It’s perfectly normal to have different functions from the same module running in different processes — there’s no special relationship between modules and processes. A module is just a collection of functions, and these functions can be invoked in any process.
lolwut, my noob face, one moar time for good measure tho
