### Third Edition Updates

* Algorithms using ES2015+ (ES6+)
* New data structures and algorithms
* All chapters rewritten and reviewed 
* Three (3) new chapters
* Creation of a Data Structures and Algorithms library that can be used in the browser or with Node.js
* Algorithms tested with Mocha + Chai (test code available in `test` directory)
* **TypeScript** version of the source code included (library and tests)

## Project Structure

`src/js/index.js` file contains all the data structures and algorithms listed by chapter.

```
|_examples (how to use each data structure and algorithm, organized by chapter)
|_src 
|___js (source code: JavaScript version)
|_____data-structures
|_______models (classes used by DS: Node, ValuePair, ...)
|_____others (other algorithms such as palindome checker, hanoi tower)
|___ts (source code: TypeScript version)
|_____data-structures
|_______models
|_____others
|_test (unit tests with Mocha and Chai for src)
|___js (tests for JavaScript code)
|___ts (tests for TypeScript code)
```

## Installing and running the book examples With Node

* Install [Node](https://nodejs.org)
* Open terminal/cmd and change directory to this project folder: `cd /Users/.../javascript-datastructures-algorithms` (Linux/Max) or `cd C:/.../javascript-datastructures-algorithms`
* run `npm install` to install all dependencies
* To see the examples, run `http-server html` or `npm run serve`. Open your browser `http:\\localhost:8080` to see the book examples
* Or `cd html/chapter01` and run each javascript file with node: `node 02-Variables`

## Running the examples in the browser

* Right click on the html file you would like to see the examples, right click and 'Open with Chrome (or any other browser)'

* Or open the `examples/index.html` file to easily navigate through all examples:

* Demo: [https://javascript-ds-algorithms-book.firebaseapp.com](https://javascript-ds-algorithms-book.firebaseapp.com)
