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 )
}))
}
