JavaScript Data Structure

JavaScript data structure implemented in ES6. This library covers the implementation of the basic data structures, including graph(Breath-first Search, Depth-first search), binary search tree, queue, and some sorting (Quick Sort, Merge Sort) and search algorithm for array.

The code here is rewriting from Learning JavaScript Data Structures and Algorithms to es6 with some enhancements on performance, and added the unit tests for each of the data structure.

How to install and run the test

npm install;
npm test;

How to commit the code to release a new version via semantically-released

npm run commit;
 

Usage

// Graph
import { Graph } from 'js-data-structure';
const graph = new Graph();
graph.addVertex('A');
graph.addVertex('B');
graph.addVertex('C');
graph.addVertex('D');
graph.addVertex('E');
graph.addVertex('F');
graph.addVertex('G');
graph.addVertex('H');
graph.addVertex('I');
graph.addEdge('A', 'B');
graph.addEdge('A', 'C');
graph.addEdge('B', 'D');
graph.addEdge('C', 'F');
graph.addEdge('D', 'E');
graph.addEdge('E', 'G');
graph.addEdge('E', 'I');
graph.addEdge('F', 'E');
graph.addEdge('G', 'H');
graph.addEdge('H', 'I');

// get the shortest path

console.log(Sorting.bubbleSort([5, 4, 3, 2, 1]));
