First JS build tool I've used, that I have been actually immensely impressed with. Manages complexity really nicely, and does so that delivers immense value.
Porting all my projects to it as time permits.
I wrote this, am happy to field questions here.
Can a mod put a more helpful title, with something like "JavaScript build tool" so people know what it's about?
I updated the title and hope it isn't against the HN submission guidelines.
