Just clone or fork, and npm i!

These may not be the best solutions. I'm welcome to better/ more performant ones :D

It would be good to have a list of different code styles, and see how they each evolve as the test grow.

const findY = grid => grid.findIndex(row => row.includes(1))

const findX = grid => grid[findY(grid)].indexOf(1);

const findPosition = grid => ({
  x: findX(grid),
  y: findY(grid)
});
