WebApr 8, 2024 · I wrote up a detailed blog post about tail call optimization in Elixir/Erlang and its performance. The TLDR; sort of is that none tail call optimized recursive functions (body-recursive) can be faster and more memory efficient than TCO functions. This is something that I never thought before, that TCO is always faster seems to be a common … WebOct 7, 2024 · Tail Recursion To understand how the tail recursion works, let’s understand how the following code in the previous section works. Syntax len ( []) -> 0; len ( [_ T]) -> 1 + len (T). The answer to 1 + len (Rest) needs the answer of len (Rest) to be found. The function len (Rest) itself then needed the result of another function call to be found.
