Computer Science in JavaScript

Section titled “Computer Science in JavaScript”

If you find this useful, please consider supporting my work with a donation.

Description

Section titled “Description”

Collection of classic computer science paradigms, algorithms, and approaches written in JavaScript. This is the source code for the series of blog posts on my website.

Folder Structure

Section titled “Folder Structure”

The most recent packages are found in these directories:

  • src - the implementation source code
  • tests - tests for the implementation source code

These directories contain old implementations that will be replaced eventually, they are just here to avoid confusing people who find this repo through the old blog posts:

  • data-structures - data structure implementations that have not been updated yet
  • encodings - encoding implementations that have not been updated yet
  • algorithms - miscellanous algorithm implementations that have not been updated yet

As I update these, implementations will move from these folders into src.

Branches

Section titled “Branches”
  • 2009 - the branch containing all of the original implementations as reflected in my 2009 blog post series.
  • master - the branch where I’m updating the original implementations to use ECMAScript 2018 and later features.

Installing

Section titled “Installing”

You must be using Node.js v8 or later.

First, clone the repo:

$ git clone git://github.com/humanwhocodes/computer-science-in-javascript.git
$ cd computer-science-in-javascript

Then install the dependencies:

$ npm install

You can then run tests like this:

$ npm test

Updated Blog Posts (2019)

Section titled “Updated Blog Posts (2019)”

These are the most recent blog posts covering the most recent version of the code.

Data Structures

Section titled “Data Structures”

Original Blog Posts

Section titled “Original Blog Posts”

At some point I will update these blog posts for the new implementations. For now, they still refer only to the 2009 version of this code.

Data Structures

Section titled “Data Structures”

Sorting Algorithms

Section titled “Sorting Algorithms”

Other Algorithms

Section titled “Other Algorithms”

Note on Code Style

Section titled “Note on Code Style”

You may find the code style of this module to be overly verbose with a lot of comments. That is intentional, as the primary use of this module is intended to be for educational purposes. There are frequently more concise ways of implementing the details of this class, but the more concise ways are difficult for newcomers who are unfamiliar with linked lists as a concept or JavaScript as a whole.

Issues and Pull Requests

Section titled “Issues and Pull Requests”

As this is part of series of tutorials I’m writing, only bug fixes will be accepted. No new functionality will be added to this module.
