小白，请教各位大佬！async/await catch不到错误？感激不尽

Question

functionf(){returnnewPromise((resolve,reject)=>{setTimeout(()=>{reject(0)},1000)})}asyncfunctionmain(){letfunc=[];try{func.push(f());for(letiof[1,2,3]){awaitf();}awaitPromise.all(func);}catch(e){console.log(e);}}main();为什么这样会报Unhandledpromiserejection，难道f()在放进func时就执行了吗，小白求解

Answer 1

func.push(f())这句抛出的错误，f()调用的时候没await，改成下面就不会报错了：
func.push(f)
//或
func.push(awaitf())
