# Challenge \#18: 🎄 Lights in line with diagonals 





MEDIUM

The Christmas lights panel 🎄✨ in the workshop has been a total success. But the elves want to go one step further: now they want to detect whether there is a **line of 4 lights of the same color** also on a **diagonal**.

The panel is still a **matrix** where each cell can be:

- `'.'` → light off
- `'R'` → red light
- `'G'` → green light

Now your function must return `true` if there is a line of 4 lights of the same color that are on and aligned, whether **horizontally ↔, vertically ↕ or diagonally ↘↙**.

```javascript
hasFourInARow([\
  ['R', '.', '.', '.'],\
  ['.', 'R', '.', '.'],\
  ['.', '.', 'R', '.'],\
  ['.', '.', '.', 'R']\
])
// true → there are 4 red lights in a ↘ diagonal

hasFourInARow([\
  ['.', '.', '.', 'G'],\
  ['.', '.', 'G', '.'],\
  ['.', 'G', '.', '.'],\
  ['G', '.', '.', '.']\
])
// true → there are 4 green lights in a ↙ diagonal

hasFourInARow([\
  ['R', 'R', 'R', 'R'],\
  ['G', 'G', '.', '.'],\
  ['.', '.', '.', '.'],\
  ['.', '.', '.', '.']\
])
// true → there are 4 red lights in a horizontal line

hasFourInARow([\
  ['R', 'G', 'R'],\
  ['G', 'R', 'G'],\
  ['G', 'R', 'G']\
])
// false → there are no 4 consecutive lights of the same color
```

**Note:** The board can be any size.
