Return Multiple Values in Javascript?

Return multiple values in JavaScript

As a JavaScript developer, you may come across situations where you need to return multiple values from a function. While JavaScript doesn’t have built-in support for returning multiple values like some other programming languages, there are several ways to achieve this functionality. In this article, we will explore three common approaches to return multiple values in JavaScript.

1. Using an Object

One way to return multiple values in JavaScript is by using an object. You can create an object and assign the values to different properties of the object. Then, you can return the object from the function.

function returnMultipleValues() {
  const value1 = 'Hello';
  const value2 = 'World';
  
  return {
    value1,
    value2
  };
}

const result = returnMultipleValues();
console.log(result.value1); // Output: Hello
console.log(result.value2); // Output: World

2. Using an Array

Another approach is to use an array to return multiple values. You can create an array and push the values into the array. Finally, you can return the array from the function.

function returnMultipleValues() {
  const value1 = 'Hello';
  const value2 = 'World';
  
  return [value1, value2];
}

const result = returnMultipleValues();
console.log(result[0]); // Output: Hello
console.log(result[1]); // Output: World

3. Using Destructuring Assignment

The third approach involves using destructuring assignment to extract multiple values from an array or object. This can be useful when you have an existing array or object and want to extract specific values.

function returnMultipleValues() {
  const value1 = 'Hello';
  const value2 = 'World';
  
  return [value1, value2];
}

const [result1, result2] = returnMultipleValues();
console.log(result1); // Output: Hello
console.log(result2); // Output: World

These are three common approaches to return multiple values in JavaScript. Depending on your specific use case, you can choose the approach that best suits your needs. Whether it’s using an object, an array, or destructuring assignment, these techniques will help you handle situations where you need to return multiple values from a function.

Happy coding!
