Gleam is a statically-typed language,[8] which is different from the most popular languages that run on Erlang’s virtual machine BEAM, Erlang and Elixir.
Example edit
import gleam/io
pub fn main() {
io.println("hello, friend!")
}Gleam supports tail call optimization:[9]
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)
}
