/*Write a program that creates a string that represents an 8×8 grid, using newline characters to separate lines. At each position of the grid there is either a space or a “#” character. The characters should form a chess board.*/

var size = 8;
var board = "";

for (var y =0; y< size; y++) {
  for(var x =0; x< size; x++){
  if ((x+y) %2 ===0)
    board += " ";
