async/await 实现 promise 红 绿 蓝灯问题

Question

前言
之前网上有一个promise实现红绿蓝灯交替亮的问题，我再次描述一下问题。
题目：红灯三秒亮一次，绿灯一秒亮一次，黄灯2秒亮一次；如何让三个灯不断交替重复亮灯？（用Promse实现）
functionred(){
console.log('red');
}
functiongreen(){
console.log('green');
}
functionyellow(){
console.log('yellow');
}
然后我最近学习asyncawait的时候来试着实现这个功能。但是我觉得我写的代码不太好，但是又不知道怎么优化，在此贴出希望有人给点建议来优化一下感谢ing！
functionred(){
console.log('red');
}
functiongreen(){
console.log('green');
}
functionblue(){
console.log('blue');
}
functionmiddle(cb,time,time1){
returnnewPromise((resolve,reject)=>{
setTimeout(()=>{
cb();
resolve(time1);
},time);
});
}
asyncfunctionsetp1(){
constrTime=awaitmiddle(red,3000,1000);
constgTime=awaitmiddle(green,rTime,2000);
constbTime=awaitmiddle(blue,gTime);
setp1();
}
setp1();

Answer 1

functionred(){console.log('red');}functiongreen(){console.log('green');}functionblue(){console.log('blue');}functionwait(time){returnnewPromise((resolve,reject)=>{setTimeout(resolve,time)})}asyncfunctionmarquee(){awaitwait(3000)red()awaitwait(1000)green()awaitwait(2000)blue()marquee()}marquee()

Answer 2

两个参数就够啦functionred(){console.log('red');}functiongreen(){console.log('green');}functionblue(){console.log('blue');}functionmiddle(cb,time){returnnewPromise((resolve,reject)=>{setTimeout(()=>{cb();resolve();},time*1000);});}asyncfunctionsetp1(){constrTime=awaitmiddle(red,3);constgTime=awaitmiddle(green,1);constbTime=awaitmiddle(blue,2);setp1();}setp1();
