Conway's 'Game of Life' in ReactJS

I developed this app to get familar with ReactJS. See it here: http://conwaysgol.azurewebsites.net

Conway's Game of Life is a cellular automation by the British mathematician John Horton Conway in 1970.

Rules:

1. Any live cell with fewer than two live neighbors dies, as if caused by underpopulation.
2. Any live cell with two or three live neighbors lives on to the next generation.
3. Any live cell with more than three live neighbors dies, as if by overpopulation.
4. Any dead cell with exactly three live neighbors becomes a live cell, as if by reproduction.
