A simple iterator library for JavaScript meant for exploration of Transducers.
Inspired by experimental ES7syntax proposed by Kevin Smith (@zenparsing).
Also heavily influenced by C# Linq
Here is a good explanation on Transducers using JavaScript, though the approach is very different. Understanding Transducers in JavaScript
- Uses ES6 via Babel
- Expect (https://github.com/mjackson/expect)
Installation:
git clone [email protected]:dax70/libfree.git
cd libfree
npm install
Run tests to see API usage and working code.

There has been a proposal for ES7 (EcmaScript 2016) for function binding syntax for a while.
Here is an example from the proposal and using an iterator library as an example.
/* ES7 */
import { map, takeWhile, forEach } from "iterlib";
getPlayers()
::map(x => x.character())
::takeWhile(x => x.strength > 100)
::forEach(x => console.log(x));
As you may notice, in this case it enables a now common pattern in Javascript thanks to jQuery, namely the Fluent Interface, but more on that later.
Development:
- Build once:
npm run webpack - Run dev server:
npm start- Web page: http://localhost:8080/
- Keep the console open to see errors and warnings
