AnimeJs v4 introduces significant improvements in web animations, focusing on smoother interactions, especially for mobile browsers. User feedback highlights how the new version enhances scrolling experiences, praise for the complex animated landing page, and overall excitement about its performance, especially regarding layered interactive elements. Users noted the compatibility with unconventional browsers, indicating a broadened accessibility for developers. However, there was a feedback regarding the responsive layout where the scroll resets on window resizing, which can affect usability. Overall, the launch seems poised to motivate developers to dive into JavaScript for animation purposes and showcases an evolution in web technologies since the era of DHTML.
