Data Structures in Javascript

A package containing implementations of various data structures in Javascript. This project is mainly a learning exercise and personal refresher on the common CS data structures, in addition to playing around with test coverage reports with coveralls

Installation

npm install @jasonheecs/js-data-structures --save

Data Structures

• Binary Search Tree
• Singly Linked List
• Doubly Linked List
• Circular Linked List
• Queue
• Stack
• Trie
• Min Heap
• Graph

Usage

    var {BST} = require('@jasonheecs/js-data-structures');
    var {List} = require('@jasonheecs/js-data-structures');
    var {Trie} = require('@jasonheecs/js-data-structures');

    var bst = new BST();
    bst.add(10);
    bst.add(5);
    bst.add(15);

    console.log(bst.inOrder()); // [5, 10, 15]


    var linkedList = new List();
    linkedList.add(1);
    linkedList.add(2);
    linkedList.add(3);

    console.log(linkedList.search(2)); // Node { value: 2, next: Node { value: 3, next: null } }


    var trie = new Trie();
    trie.addWord('cat');
    trie.addWord('car');
    trie.addWord('dog');

    console.log(trie.find('ca')); 
    /** Node { value: 'a', children: Map {
         't' => Node { value: 't', children: Map {}, isCompleteWord: true },
         'r' => Node { value: 'r', children: Map {}, isCompleteWord: true } },
        isCompleteWord: false } **/

Running unit tests

npm test

To run a specific test file, you can use an extra -- to pass the filename through:
npm test -- test/binary-search-tree-test.js
