Type args in typescript

Question

I have this situation in my typescript code:

const first = (value: any[]) => {

}
const test = (...args: any[]) => first(...args);

In function test I pass all params in first function. first(...args).

Doing this I get a typescript error: A spread argument must either have a tuple type or be passed to a rest parameter.(2556).

I notice many answers on this topic but they don't solve my issue.

How to solve this issue?

Answer 1

The error means that you need to use an Array and spread arg within it:

const first = (value: any[]) => {};
const test = (...args: any[]) => first([...args]);

Answer 2

Your first() function expects to get an array/tuple.
So you can simply pass the array.

const first = (value: any[]) => {};
const test = (...args: any[]) => first(args);

or you can make the first method accept variable arguments:

const first = (...value: any[]) => {};
const test = (...args: any[]) => first(...args);
