Objects

Пусть у нас есть такой объект:

const RADIO_CARD_GROUP_THEME = {
  VERTICAL: 'vertical',
  HORIZONTAL: 'horizontal',
}

Мы можем сделать такие типы:

type KEYS_TYPE = keyof typeof RADIO_CARD_GROUP_THEME; // будет "VERTICAL" | "HORIZONTAL"
type VALUES_TYPE = (typeof RADIO_CARD_GROUP_THEME)[KEYS_TYPE]; // будет 'vertical' | 'horizontal'
