How to return multiple values ​​from a JavaScript homebrew function

This article explains how to return multiple values ​​from a JavaScript function.

Is there a way to return multiple values ​​from a function?

There are two ways to return multiple values: using arrays and objects, and using tables.

How to return multiple values ​​from a function using arrays and objects

You can return multiple values ​​by defining an array or object as the return value of a function .

If you want to return multiple values ​​using an array, you can use the following code, for example.

function getValues() {
  return [1, 2, 3];
}

const result = getValues();
console.log(result); // [1, 2, 3]

You can also use objects as well.

function getValues() {
  return {
    value1: 1,
    value2: 2,
    value3: 3
  };
}

const result = getValues();
console.log(result); // { value1: 1, value2: 2, value3: 3 }

Sample imitating a tuple

In JavaScript, there is no concept of tuples, but you can achieve tuple-like behavior by returning an array containing multiple values .

For example, consider the following code:

function getValues() {
  return [1, 2, 3];
}

const [value1, value2, value3] = getValues();
console.log(value1, value2, value3); // 1 2 3

Summary of this article

We explained how to return multiple values ​​from a function.

Returning multiple values ​​from a JavaScript function can be achieved using arrays, objects, and tuples.

You’ve created a function that returns multiple values!

It is important to choose a method that suits your data structure and usage.
