// Create a function that receives a (square) matrix and calculates the sum of both diagonals (main and secondary)
// Matrix = array of n length whose elements are n length arrays of integers.
// 3x3 example:
// diagonals( [
  // [ 1, 2, 3 ],
  // [ 4, 5, 6 ],
  // [ 7, 8, 9 ]
// ] ); 

// returns -> 30 // 1 + 5 + 9 + 3 + 5 + 7

function diagonals() {
  //Solution here
