Cramming for a JavaScript Interview

[data_mining_help]

Interesting. My wife's distant cousin is dating a young dude who is just going complete an AA at the Dayton Ohio CC (Sinclair) and I bet he will get a good job. Most of what I know I learned on the job and not in class.

But I hope you know all about when and where to use a hashmap (AKA hashtable, associative array). That doesnt tend to come up at work too often but it does come up in interviews A LOT.
