game.js code:游戏.js代码：

var buttonColours = ["red", "blue", "green", "yellow"];
var gamePattern = [randomChosenColour];

function nextSequence(params) {
    var randomNumber = Math.floor(Math.random() * 4);
    var randomChosenColour = buttonColours[randomNumber];
    gamePattern.push(randomChosenColour);

}

Answer 1

It is because by the time you declare gamePattern , randomChosenColour is not defined yet.这是因为在您声明gamePattern时， randomChosenColour尚未定义。

You just need to declare the gamePattern array to be an empty array.您只需将gamePattern数组声明为空数组即可。

var gamePattern = [];
