You have cases in which you don't return anything.在某些情况下,您不返回任何东西。
if (conditionA){
return ...;
} else if (confitionB) {
return ...;
}
// Nothing gets returned
You should add a return at the end of your function for when coditionA
and coditionB
are both false
当
coditionA
和coditionB
都为false
时,您应该在 function 的末尾添加一个 return
