javascript - Eloquent JS : Chessboard – why is first row misaligned?

Question

function chessBoard (size) {
    result = "";
    for (var s = 1; s <= size; s++ ){
        for (var c = 1; c <= size; c++){
            if ((s + c) % 2 == 0) {
                result = result + " ";
            }
            else {
                result = result + "#";
            }   
        }
        result = result + "\n";
    }
    console.log(result);
}
 chessBoard(8);

结果:

  # # # #
# # # # 
 # # # #
# # # # 
 # # # #
# # # # 
 # # # #
# # # # 

为什么这段代码中“棋盘”结果的第一行没有对齐？帮助我了解需要更改的内容。它应该看起来像:

# # # #
