[Rust] Rust is pulling base, Javascript is pushing based

Typescript

import * as fs from "fs";

fs.readFileSync("project/lines", { encoding: "utf-8" })
  .toString()
  .split("\n")
  .filter((_, i) => i % 2 === 0)
  .filter((_, i) => i > 1 && i < 4) // skip(2).take(2)
  .forEach((line) => {
    console.log(line);
  });

 

Rust:

fn main() {
    let file = std::fs::read_to_string("project/lines").unwrap();
    file    
        .lines()
        .enumerate()
        .filter(|(idx, _)| idx % 2 == 0)
        .skip(2)
        .take(2)
        .for_each(|(_, line)| println!("{}", line));
}
