I use JavaScript when competing in Code Jam, and one of the things I noticed was that multidimensional arrays are a bit of a hassle, so I decided to create a helper class for that purpose.

Coming from a Java background, the Arrays class came to mind, so I decided to reuse most of the API in my implementation.

So, introducing Arrays.js!

It comes with unit tests for all its functionality, but if I missed something, feel free to open an issue. Also, it’s released under the permissive MIT license.
