title: Major JavaScript Data Structures
body: <p>I have a job interview coming up, and one of the core technologies of the company is JavaScript.  I was told that the next interview will focus on JS Data Structures, a term that never came up in any of my education.  I have spend a while on Google trying to find out more about them, and the best thing I could come across was <a href="http://en.wikipedia.org/wiki/List_of_data_structures" rel="noreferrer">this Wikipedia page</a>.</p>
  
  <p>As you can tell, the list of items is quite long and way too much to study before my interview.  Since the Wiki article is generic and not JS specific, I know that some (most?) of what's on there does not apply to JS.  Can I get some help on what are the main data structures and what I should focus my time on?  I was unable to find an answer to that on Google.</p>
  
  <p>I know Arrays are one of the major ones that I will need to know.  What are the other major data structures I should be prepared to talk about?</p>
  
  <p>Thanks for any help!!!</p>
