Challenge 1 / 1

Suppose we have a Stimulus controller like this:

export default class extends Controller {
    static targets = ['selectItem'];

    static values = {
        itemId: Number
    }
}

How would you add a change callback method for the itemId value?

itemIdChanged() {
    ...
}

itemIdValueChanged() {
    ...
}

onChangeItemIdValue() {
    ...
}

itemIdValue() {
    ...
}
