How to compare cuids #233

First off, thank you for creating this useful package.

I have a requirement where I need to compare the generated cuids. I understand from the source that the generated cuids are base 36 numbers converted to strings. Taking a couple of generated cuids as an example, would following be the correct way to compare these cuids?

parseInt('ckqs83wwv00033d61mvknp45t', 36) > parseInt('ckqs81yqg00013d61fyap1rtz', 36)

This operation is generally not recommended in application space. Applications should not rely on the ids to tell you anything except the identity of an entity. If you want to sort things by creation date, we recommend saving the data with a createdAt field and sorting by that, instead of cuid.

If you're implementing something outside of application space, is there a good reason you can't use the default lexicographical sort order with string >, <, === in JavaScript?
