The general aim is to make building web content fun and easy and driven by creativity, passion and innovation. The library was initially released on July 27, 2005 and has undergone many revisions, improvements and releases since then bringing it to the current version of 1.4, a testament to the developer's ongoing dedication to making the product as good as it can be. It is released under a dual license in MIT or the Academic Free License 2.1 flavors, which allows you to use the library for anything that you want and to make whatever changes or modifications you see fit, which makes it ideal for use in your own products or web sites.
The MochiKit site is very well produced and is presented in a clear, attractive and no-nonsense style. You can view demos of MochiKit in action, read the library's documentation and find out who else is using MochiKit in their projects. There is a blog to keep up to date on the latest MochiKit developments, and of course links to the latest downloads of the two library versions. The demo's section on the whole is very good and provides clear examples of some of the functionality you can add to your web sites using the library. The only problem with the examples is that there isn't a great deal of them; although this is noted by the developers and more examples are promised.
