You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: simple_list.rs
    path of file: ./repos/dioxus/examples
    
    the code of the file until where you have to start completion: //! A few ways of mapping elements into rsx! syntax
//!
//! Rsx allows anything that's an iterator where the output type implements Into<Element>, so you can use any of the following:

use dioxus::prelude::*;

fn main() {
    launch_desktop(app);
}

fn app() -> Element {
    rsx!(
        div {
            // Use Map directly to lazily pull elements
            {(0..10).map(|f| rsx! { "{f}" })},

            // Collect into an intermediate collection if necessary, and call into_iter

    
fn app() -> Element {
    rsx!(
        div {
            // Use Map directly to lazily pull elements
            {(0..10).map(|f| rsx! { "{f}" })},

            // Collect into an intermediate collection if necessary, and call into_iter
            {["a", "b", "c", "d", "e", "f"]
                .into_iter()
                .map(|f| rsx! { "{f}" })
                .collect::<Vec<_>>()
                .into_iter()},

            // Use optionals
            {Some(rsx! { "Some" })},

            // use a for loop where the body itself is RSX
            for name in 0..10 {
                div { "{name}" }
            }

            // Or even use an unterminated conditional
            if true {
                "hello world!"
            }
        }
    )
}
