Is it possible for a primitive value to function as a type within Typescript?

Is it possible for a primitive value to be considered as a type in Typescript?

For example, is the type below considered valid? If not, how can it be modified to make it valid?

export type Status = {
    completed: false;
}

Answer №1

Absolutely, it is possible. The resources provided by the TypeScript Documentation demonstrate how setting a primitive literal can serve as the expected type. However, relying solely on one literal type may not always be advantageous. In the context of your code, utilizing a type union allows for showcasing various literal values that can be assigned to completed:

export type Status = {
    completed: false | 0 | "NO";
}
