console.log(process) //这个是node自带的

var playAction = process.argv[process.argv.length - 1]
console.log(playAction)
var random = Math.random() * 3

if (random < 1) {
    var computerAction = 'rock'
} else if (random > 2) {
    var computerAction = 'sicssor'
} else {
    var computerAction = 'paper'
}

if (playAction === computerAction) {
    console.log('平局')
} else if (
    (computerAction === 'rock' && playAction === 'paper') ||
    (computerAction === 'sicssor' && playAction === 'rock') ||
    (computerAction === 'paper' && playAction === 'sicssor')
) {
    console.log('你赢了')

} else {
    console.log('你输了')

}

process.exit() //杀进程
