Is it possible to compress an Array comprised of nested Arrays?

I am working on a function that takes in a specific type structure:

type Input = [Array<string>, Array<number>, Array<boolean>];

It then transforms and outputs the data in this format:

Array<[string, number, boolean]>

This essentially flattens the nested array into a single array.

I'm trying to figure out how I can achieve this using generics. Currently, my function signature looks like this:

function foo<T extends Array<Array<unknown>>>(arrays: T) {

}

I believe I need to apply some kind of transformation to the generic type 'T'. What would be the correct transformation to implement?

typescript

Answer №1

Define a type Unarrayify<T> which transforms arrays within an object into individual elements, resulting in a new type with non-array values only.

For example, defining MyType as Unarrayify<[Array<number>, Array<string>, Array<boolean>]> would result in the type [number, string, boolean].

A function foo<T> is then declared, expecting an array input 'arrays' of type T and returning an array of Unarrayify<T>.
