This is a collection of different data structures and utilities, implemented in JavaScript. Its written and tested using Node.js which is also the target platform.

• Maps

  *

  Sorted Maps

  Maps sorted according to natural ordering of keys or by comparator function provided at creation time. Two different backing stores are available * [AVLTree](http://monmohan.github.io/dsjslib/AVLTree.html) * [Skip List](http://monmohan.github.io/dsjslib/SkipList.html) *

  Tries

  Map optimized for prefix searching on string keys * [Multi Way Trie](http://monmohan.github.io/dsjslib/RWayTrie.html) * [Ternary Search Trie](http://monmohan.github.io/dsjslib/TernarySearchTrie.html) *

  Multi-Valued

  Map supporting multiple values for a key * [MultiMap](http://monmohan.github.io/dsjslib/MultiMap.html) * [TreeMultiMap](http://monmohan.github.io/dsjslib/TreeMultiMap.html) - In addition, Map is sorted on keys. Uses AVLTree as backing store

• Queues

  *

  [Linked Deque](http://monmohan.github.io/dsjslib/LinkedDeque.html)

  - An optionally capacity constrained deque based on linked nodes *

  [Priority Queue](http://monmohan.github.io/dsjslib/PriorityQueue.html)

  - Priority Queue based on a Binary Heap *

  [Delay Queue](http://monmohan.github.io/dsjslib/DelayQueue.html)

  - Queue of 'Delayed' items, item can only be taken when its delay has expired. For example usage see [wiki: DelayQueue-for-Scheduled-Task-Management](https://github.com/monmohan/dsjslib/wiki/Example:-DelayQueue-for-Scheduled-Task-Management)

• Utilities

  *

  [LRU Cache with Stats](http://monmohan.github.io/dsjslib/Cache.html)

  Google Guava inspired LRU cache. [Reference: Google Guava](https://code.google.com/p/guava-libraries/]. In-memory LRU cache implementation for Node, inspired by Google Guava Loading Cache . The cache is simpler since it doesn't have to deal with concurrent threads, but other functionality of Guava cache are captured like - Auto loader function - Removal listener - Auto expiry After Write (TTL) - Max Size and weight - Cache Stats recording For usage and overview see wiki: https://github.com/monmohan/dsjslib/wiki/LRU-Cache-Feature-and-usage-overview

  • [BitSet](http://monmohan.github.io/dsjslib/BitSet.html)

    - An array of bits with operations to set, examine and clear individual bits

  • [BTree](http://monmohan.github.io/dsjslib/BTree.html)

    - Self balancing generalized Search Tree

    npm install dsjslib

Current version 0.6.6 is stable and thoroughly tested on Node v0.10
