Hi guys, happy to see `mojs` here! I'm the person who've started the project and would be more than happy to answer any questions you have.
In any case, thank you for creating this and hope to see this project continue to grow.
You've done an amazing job creating an amazing library. One that I advertise every opportunity I get. Thank you!
I was doing a lot of animation work and there was a lack of animation tools I've got used to, so I've started to write modules myself. After a while, I noticed the system in what I've written so decided to release it.
As for maintaining part - it is heavily covered with unit and environmental tests, of course, it adds some overhead but ensures that your tool is robust and works in every browser.
It is a side project and we still expect more contributions from the community.
