/*
|
|
* This is the HTML/JavaScript for the game board component.
|
|
* The "template" variable at the top defines the HTML for this component. It can contain references
|
|
* to methods and properties on the "GameBoardComponent" class shown below.
|
|
*
|
|
* For example, the "greeting" property is referenced in the template as "{{ greeting }}". When
|
|
* the page loads, this will be replaced by the value of the "greeting" property.
|
|
*
|
|
* The class below manages the logic referenced by the template. Then, we can use the component
|
|
* in the application by creating an HTML tag with the value of the "selector()" getter.
|
|
*
|
|
* In this case, that's the <app-game-board></app-game-board> tag in index.html.
|
|
*
|
|
* We can also use components w/in components, to keep code clean. For example, we could have
|
|
* a battleship component that we reference inside this game board component.
|
|
*
|
|
* Battleship grid is 14x14.
