Usage

Use constructor

// in browser or node
import { iterator } from '@syrflover/iterator';

// in deno
import { iterator } from 'https://raw.githubusercontent.com/syrflover/iterator-helper/master/mod.ts';

iterator([1, 2, 3, 4, 5, 6])
    .filter((e) => e % 2 === 0)
    .map((e) => e + 1)
    .sum()
    .then((r) => logger.info(r)); // 15

Use ArrayLike.prototype.iter

// in browser or node
import '@syrflover/iterator/dist/types/global';

import 'https://raw.githubusercontent.com/syrflover/iterator-helper/master/deno/types/global.ts';

[1, 2, 3, 4, 5, 6]
    .iter()
    .filter((e) => e % 2 === 0)
    .map((e) => e + 1)
    .sum()
    .then((r) => logger.info(r)); // 15
