About
Utility functions for iterators. Inspired by Rust’s
std::iter::Iterator
trait. This library uses JavaScript native iterators, so it’s compatible with
any library that uses them.
Array.prototype
methods
Difference from This library’s functions are lazy. They don’t evaluate the whole iterator at once. They evaluate only the needed elements. This is useful when you have a large iterator and you only need a few elements from it.
Example
import {
filter,
forEach,
map,
pipe,
take,
} from "https://deno.land/x/iter_funcs@1.1.0/mod.ts";
const array = [1, 2, 3, 4, 5, 6];
pipe(
array.values(), // make iterator from array
filter((x) => x % 2 === 0), // filter even numbers
map((x) => x * 2), // multiply by 2
take(2), // take first 2 elements
forEach(console.log), // => 4, 8
);
