The function can operate either on the ‘board’ array if the value for ‘piece’ is COMPUTER, or
the ‘cBoard’ array if the value for ‘piece’ is PLAYER. Again when scanning a row the first square
must be empty, the next must contain an opponent piece and the final must be a player piece. If
all the conditions are passed then true is returned; otherwise false is returned.
1 function scanArray(i, piece, incX, incY){

var name, n, inc;
4 inc = incY*8 + incX;

n = i + inc;
7 //Must be at least one

9 case PLAYER:
10 if (cBoard[i]!=1 || cBoard[n]!=COMPUTER) return false;
11 do{
12 n += inc;
13 }while(cBoard[n] == COMPUTER);

Once the best computer score is evaluated the function ‘adjustArray’ is called:
1 function adjustArray(i, piece){
2 if (flip[0]) flipArrayLine(i, piece, 1, 0);
3 if (flip[1]) flipArrayLine(i, piece, 0, 1);
4 if (flip[2]) flipArrayLine(i, piece, -1, 0);
5 if (flip[3]) flipArrayLine(i, piece, 0, -1);
6 if (flip[4]) flipArrayLine(i, piece, -1, -1);
7 if (flip[5]) flipArrayLine(i, piece, 1, -1);
