How to not allow two keys to be pressed in a row in JavaScript?

Question

Im making a snake game and need some code to not allow the same key to be pressed in a row. So for example if 'w' is pressed, it wont be able to be pressed again until another key is pressed. Anyone now the simplest way to achieve this? Thanks

当您收到按键事件时，保存上次按下的按键并检查新按键是否相同，然后从函数中返回。
