# Memory!

Tonight you are going to build the game called: [Memory](https://en.wikipedia.org/wiki/Concentration_(game)). We have provided you with a few starter files. You will look at the `index.html` to set up your physical board and cards, but write the code in your `app.js` file to get your game to work.

Take it one step at a time. Follow these instructions to help get you going.


### You will need

#### Data

- an array of ten tiles
	- your ten 'tiles' will represent the letter values that will be displayed on each DOM tile. eg. ['A', 'A', 'B', 'B', etc.]

**Commit 1** <br>
<hr>
The commit message should read: <br>
"Commit 1: Created an array to hold my ten game tiles"
<hr>

#### Functions

- `start()`
	- shuffle the tiles array
	- then call makeAndDisplayTiles to build and display the gameboard

**Commit 2** <br>
<hr>
The commit message should read: <br>
"Commit 2: Created start() function"
<hr>

- `makeAndDisplayTiles()`
	- it should create 10 new game tiles (you will want to use a loop to create these tiles)
		- give them the class 'column'
		- give them a 'data-value' attribute from each element of your tiles array. Ex: The output for an 'A' tile will look like ` <div class="column" data-value="A"></div> `
		- it should add click events to each of the gameboard tiles
			- Each click event should call the makePlay function passing it the tile that was clicked. Strong hint: the tile that was clicked is `this` tile . . . Can you pass `this` as a parameter to the makePlay function? Test it out.
		- add the game tiles to the board
	- it should clear the text in the `info` div
	- this function should empty the container that will hold the gameboard tiles

**Commit 3** <br>
<hr>
The commit message should read: <br>
"Commit 3: Created makeAndDisplayTiles() function"
<hr>

- `makePlay(tile)`
	- this function should set the text of the current clicked tile to the value stored in the data attribute
	- it should add a class of found to the tile
	- it should add a class of clicked to the tile
	- if the number of clicked tiles is 2, then it should check for a match (hint: You might want to make an array to hold your clicked tiles. Check the length of the array of clicked items... if it's 2, you're good to go!).

**Commit 4** <br>
<hr>
The commit message should read: <br>
"Commit 4: Created makePlay(tile)"
<hr>

- `checkForMatch()`
	- this should retrieve the data-value of the two clicked tiles
	- if they are a match
		- the 'clicked' class should be removed from the tiles
		- the click event should be turned off for those tiles
		- should check for a win
	- if no match is found
		- the text of the clicked cards should be set back to empty
		- the found and clicked classes should both be removed
		- BONUS: use setTimeout to keep your cards showing for a hot
		  moment.

**Commit 5** <br>
<hr>
The commit message should read: <br>
"Commit 5: Created checkForMatch() function"
<hr>

*After you have the preceding functions working:*
- `checkForWin()`
	- if the number of found tiles is 10
		- add a winning message to the info div
		- remove the found class
		- add a won class

**Commit 6** <br>
<hr>
The commit message should read: <br>
"Commit 6: Created checkForWin() function"
<hr>

## START

- add a click event to the start button, so that when it is clicked a new game is triggered.

**Commit 7** <br>
<hr>
The commit message should read: <br>
"Commit 7: Added a click event to the start button to start a new game"
<hr>
