Hello everyone, this is a quick tutorial, In my work, I wanted to avoid duplicating code as I can and abstract things for example if I use an enum named Weekdays and it contains the following data:
enum Weekdays = {
MONDAY = 'mon',
TUESDAY = 'tue',
WEDNESDAY = 'wed'
}
Let's say you want to create a type called WeekdayType which should contain 'mon' | 'Tue' | 'Wed', how we can do this? Starting from version 4.1 you can do a tricky thing to do it in a single line of code, let's see it.
type WeekdayType = `${Weekdays}`;
// WeekdayType = 'mon' | 'Tue' | 'Wed'|
Congratulations, you did it! Awesome, right?
