Absolute

In this medium-level challenge, you'll implement the Absolute<T> type. a type that take string, number or bigint and returns a positive number string.

type Test = -100
type Result = Absolute<Test> // expected to be "100"

Detailed Explanation

type Absolute<T extends number | string | bigint> = `${T}` extends `-${infer V}`
  ? V
  : `${T}`

How it works:

• First we constrain the type T to be a number, string or bigint.
• Then we use a template literal to check if the type is a negative number.
• If it is, we use the -${infer V} to capture the positive number.
• If it is not, we return the type as is (T).

This challenge helps you understand TypeScript's advanced type system and how to apply this concept in real-world scenarios.
