Do you know IxJS?
I do. Both serve the same use case, I just think iter-tools is better. A lot better actually! I've put quite a lot of my own work into it to make that be the case.
For one thing it has API docs, making it semver compliant where IxJS is not.
It also offers all its methods in both sync and async forms, which Ix does not.
I'm also fairly sure that it has vastly superior test coverage.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
