A standalone implementation of hash table in JavaScript. It associates keys with values, and allows any object to be used as the key (unlike JavaScript's built-in Object, which only allows strings as property names).

jshashtable requires no libraries and is designed to work in all ECMAScript 3 compliant environments, including all major browsers. In particular, it has been tested and works in:

• Firefox (all versions, back to Phoenix 0.1)
• Internet Explorer 5+
• Safari 3+ (untested in previous versions)
• Google Chrome (all versions)
• Opera 7+

See the jshashtable website for full documentation.

Version 2.0 released

Version 2.0 is released today (30th December 2009). It features big performance improvements (typically 200% speed increase for put and get operations) and adds a few new methods: clone(), putAll(), entries() and each(). Also, the compressed JS file is slightly smaller than in version 1.0 at just under 4K.
