Is the return value a result of destructuring?

function display(): (number, string) {
    return {1,'my'}
}

The code above is displaying an error. I was hoping to use const {num, my} = print(). How can I correctly specify the return type?

Answer №1

Consider implementing a tuple in your code. Here's an example:

function display(): [number, string] {
    return [1,'example']
}

const [numValue, stringValue] = display();

For a live demonstration, check out the Typescript Playground

Answer №2

To obtain a result consisting of both a string and a number, you must create an object with specific property names. This defines the return type that should be utilized within your function.

type myReturnType = {
  n: number,
  s: string
}

function generateResult():myReturnType {
   return {n:1,s: 'example'}
}

let {n, s} = generateResult();

Below is a condensed version of the previous code snippet:

function generateResult():{n: number, s: string}{
    return {n:1,s: 'example'}
}

let {n, s} = generateResult();
