I like that the code is easy to understand. Most of the functions are straight forward and easy to use. I dislike that the documentation is not as well organized as I might like. There are a lot of functions that are not properly documented. This makes it harder to use the library. I am using Sequence.js to help create some animated graphics for my clients. It has been helpful in creating some of the graphics that I need to create. I dislike that I have to do a lot of research on Sequence.js to figure out how to create the animation that I need. Sequence.js has helped me create some of the graphics that I need to do. It has helped to make my life easier.
