I'm building a the tic tac toe game (a project on Free Code Camp), and have implemented a minmax algorithm to decide which square the computer player should choose next. It is working as expected in all cases I have tested, except for the following: var userIs = 'o' var computerIs = 'x' function countInArray(array, what) { var count = 0; for (var i = 0; i < array.length; i++) {
我正在构建一个tic tac toe游戏(Free Code Camp上的一个项目),并且已经实现了一个minmax算法来决定下一个计算机玩家应该选择哪个方块。 它在所有我测试过的情况下都能正常工作,除了以下情况: var userIs = 'o' var computerIs = 'x' function countInArray(array, what) { var count = 0; for (var i = 0; i < array.length; i++) { if (array[i] === what) { count++; } }
