Randomly generates User-Agent strings based on actual browser market share and usage statistics.
The version numbers generated are sane, however, revisions are totally random and unlikely to exist in the wild.
I decided not to include language selection found in the PHP version and instead include all the languages in the ISO639-2 standard because it's atypical for sites to determine client locale based on the user-agent.
var random_ua = ;console;//Easy like Sunday morning//You can easily use random_ua to generate a random User-Agent for an HTTP request:var http = ;http;
Please send your suggestions for improvements or updates.
This script is roughly based upon Luka Pusic's PHP script: http://360percents.com/posts/php-random-user-agent-generator/
A refactored version in PHP is available on GitHub at: https://raw.github.com/mwhite/random-uagent/
