What's your favorite data structure?

I find myself finding ways to use or implement variations of hash maps in my code, mainly because I love being able to perform an O(1) lookup of what I want to find.

What about you? What is your favorite data structure and why?

I like tries because it's a simple example of a tree-like structure you use every day (e.g. dictionary/spellchecker).

Although, these applications might be using DAFSA..

I like dictionaries/hashes, the key/value pair seems to work best for me. And with Javascript, you can place a function, object or array as the value! That just feels really powerful.

Sorry, it's true.
