# Function Redefinition

Nothing in the first area.

The following code in the second area:
```javascript
getRandomInt = function(){return 600;};
```

# Closures
## ZER0
```js
 
// using canvas to draw the line
var ctx = map.getCanvasContext();
ctx.beginPath();
ctx.strokeStyle = 'white';
ctx.lineWidth = 5;
ctx.moveTo(x1, y1);
ctx.lineTo(x2, y2);
ctx.stroke();
// take advantages of the closure create by `map.createLine`
// so all lasers will be of the same color of the player
color = player.getColor();
