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)
  • 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.
