-# Battleship-JavaScript
-A very very simple Battleship game written in plain JavaScript: http://learntocodela.github.io/Battleship-JavaScript/
-
-Read about the game and its rules here: https://en.wikipedia.org/wiki/Battleship_(game)
-
-### Step 1: Create your files
-
-Useful references:
-- [Final HTML file](https://github.com/LearnToCodeLA/Battleship-JavaScript/blob/gh-pages/index.html)
-- [Final CSS file](https://github.com/LearnToCodeLA/Battleship-JavaScript/blob/gh-pages/style.css)
-- [Final JS file](https://github.com/LearnToCodeLA/Battleship-JavaScript/blob/gh-pages/battleship.js)
-- [CSS Relative and Absolute Positioning](http://learnlayout.com/position.html)
-
-### Step 2: Create a grid on your HTML page for the game board
-
-Useful references:
-- [Document.getElementById()](https://developer.mozilla.org/en-US/docs/Web/API/Document/getElementById)
-- [Document.createElement()](https://developer.mozilla.org/en-US/docs/Web/API/Document/createElement)
-- [appendChild()](https://developer.mozilla.org/en-US/docs/Web/API/Node/appendChild)
-- [style property](https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/style)
-- [Loops in JavaScript](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Loops_and_iteration)
-
-### Step 3: Model the game board in JavaScript and place ships
-
-Useful references:
-- [Arrays in JavaScript](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array)
-
-### Step 4: Create event handler and write the game logic
-
-Useful references:
-- [Events in JavaScript](http://www.kirupa.com/html5/javascript_events.htm)
-- [Handling Events for Many Elements](http://www.kirupa.com/html5/handling_events_for_many_elements.htm)
-- [Handling Events - Eloquent JavaScript Chapter 14](http://eloquentjavascript.net/14_event.html)
-
-### Step 5: Play the game!
-
-Play the game here: http://learntocodela.github.io/Battleship-JavaScript/
-
-Features to implement next:
-- Display game messages within the HTML page instead of using [alert()](https://developer.mozilla.org/en-US/docs/Web/API/Window/alert)
-- Randomize placement of the ships at the start of each game
-- Make better graphics, maybe add sound effects?
-- Make a 2-player version of the game!
