JavaScript Return multiple values from function

To return multiple values from a function, you can pack the return values as elements of an array or as properties of an object.

Below are the approaches used in JavaScript to Return multiple values from a function:

Approach 1: Using Array

The approach of using an array to return multiple values from a JavaScript function involves organizing the values into an array and then utilizing array destructuring to extract and assign those values to individual variables.

Example: This example returns the array [“GFG_1”, “GFG_2”] containing multiple values. 

Javascript

function set() {
    return ["GFG_1", "GFG_2"];
}

let [x,y] = set();

console.log(x);
console.log(y);

Output

GFG_1
GFG_2

Approach 2: Using an object

The approach of using an object to return multiple values from a JavaScript function involves organizing the values into key-value pairs within an object.

Example: This example returns the object return {Prop_1: “Value_1”, Prop_2: “Value_2” }; containing multiple values. 

Javascript

function set() {

    return {
        Prop_1: "Value_1",
        Prop_2: "Value_2"
    };
}

console.log(set);

function returnVal() {
    let val = set();
    console.log("Prop_1 = " + val['Prop_1']
        + "Prop_2 = " + val['Prop_2']);
}
returnVal()

Output

[Function: set]
Prop_1 = Value_1Prop_2 = Value_2
