Is there a library for a Set data type in Javascript?

Question

Since Javascript doesn\'t have a built in set datatype has anyone come across a decent library for sets and set operations like union, intersection, etc?

Answer 1

If you just want to have access to simple union, intersection functions, you could also try Underscore.js's built-in Array functions. It also provides a lot of more useful utilities for data manipulation, so try it if you haven't.
