Gleam is a statically-typed language, which is different from the most popular languages that run on Erlang’s virtual machine BEAM, Erlang and Elixir.
Example
import gleam/io pub fn main() { io.println("hello, friend!") }Gleam supports tail call optimization:
pub fn factorial(x: Int) -> Int { // The public function calls the private tail recursive function factorial_loop(x, 1) } fn factorial_loop(x: Int, accumulator: Int) -> Int { case x { 1 -> accumulator // The last thing this function does is call itself _ -> factorial_loop(x - 1, accumulator * x) } }References
