[chouchouji]

The type of value should be string, maybe we can add type assert to pass this type check.

the value can be undefined because you can press <return> before typing anything

so it is possible that validate(undefined) gets called

we should be doing something like:

if (!value || !value.test(regex)) {
  // error
}

Thanks for your reply. The example has an initialValue value. I try to press it. It is not undefined. If I have some wrong steps, please tell me.

it does have an initial value so it means in this particular case, it can't be undefined

but as far as typescript is concerned, it can still be undefined because you might not have set the initial value

the types are currently right even though you've managed to make runtime code that never sets it as undefined

I get it. Initially, I added a non-null check. But after testing, I am confused that it should be string type. Thanks for your reply again. 🌹
