三七互娱秋招，前端笔试编程题（一）讨论

var Hero = function(name){
    if(this.constructor.name !== 'Hero') {
        return new Hero(name)
    }
    this.name = name;
    (function(){
        console.log(`Hi this is ${name}`)
    })()
    return Promise.resolve(this)
}

Promise.prototype.kill = function(num){
    return this.then(()=>{
        if(num & 1 !== 0){
            console.log(`kill ${num} 注意这里是单数`)
            return this
        }
        console.log(`kill ${num} 注意这里是复数`)
        return this
    })
}

Promise.prototype.recover = function(num){
    return this.then(()=>{
        console.log(`Recover ${num} bloods`)
        return this
    })
}

Promise.prototype.sleep = function(num){
    return this.then(() => new Promise(resolve=>{
        var timer = setTimeout(()=>{
            clearTimeout(timer)
            console.log(`sleep ${num} 秒`)
            resolve(this)
        },num * 1000 )
    }))
}
