javascript 如何return数组里每个值

Question

if(wqe!==null){if(wqe.length>1){for(vari=0;i

Answer 1

这实际问题应该是想问：某语句的执行结果随执行次数而改变，用闭包就行了，简单粗暴点可以用全局变量记录执行次数
varwqe=["aaa","bbb","ccc"];
varreturnName=((arr)=>{
leti=0;
return()=>arr[i++]
})(wqe);
console.log(returnName());//aaa
console.log(returnName());//bbb
console.log(returnName());//ccc
