Javascript versions of classic software development algorithms

JS-Algorithms

In case you want to prepare yourself for a job interview, or just need access to common data structures.

I've documented the process of creating this code here.

Description

Classic data structures and algorithms (with tests!) written in JavaScript

• Singly Linked List
• Min/Max Binary Heap
• Trie (With Pre-Order Traversal Sorting)
• Suffix Tree
• Stack (push, pop, peek, and isEmpty)
• Queue (add, remove, peek, isEmpty)
• Binary Search Tree
• Hash Table

As well as the following algorithms:

• Breadth First Search
• Depth First Search
• Binary Search
• Merge Sort
• Quick Sort
• Shuffle (Fisher–Yates)
• Smallest Enclosing Circle

Usage

If you want access to these data structures in your project, include this package.
