For my web application (in JavaScript) I want to generate short guids (for different objects - that are actually different types - strings and arrays of strings)
I want something like aX4j9Z for my uids (guids).
So these uids should be lightweight enough for web transfer and js string processing and quite unique for not a huge structure (not more than 10k elements). By saying quite unique I mean that after the generation of the uid I could check whether this uid does already exist in the structure and regenerate it if it does.
