Break down the provided Array type into distinct new types

If we have a specific type defined as:

type Tuple = [name: string, age: number, address: string];

and we are interested in creating a new type without the first element, like this:

type NewTuple = [age: number, address: string];

Is there a way to achieve this using some kind of "destructuring" for types?

type [Name, ...NewTuple] = Tuple;

In this scenario,

// Name === string
// NewTuple === [age: number, address: string]

Update:

I am aware that the following approach works but I believe there might be a more elegant solution, right?

type NewTuple = [Tuple[1], Tuple[2]]

Answer №1

Although the syntax may seem a bit complex, here is how you can achieve it:

let NewArgs = Args.includes(any) ? Args.slice(1) : []
