Return multiple values in JavaScript?

Question

I am trying to return two values in JavaScript. Is this possible?

var newCodes = function() {  
    var dCodes = fg.codecsCodes.rs;
    va

Adding the missing important parts to make this question a complete resource, as this comes up in search results.

Object Destructuring

In object destructuring, you don't necessarily need to use the same key value as your variable name, you can assign a different variable name by defining it as below:

const newCodes = () => {  
    let dCodes = fg.codecsCodes.rs;
    let dCodes2 = fg.codecsCodes2.rs;
    return { dCodes, dCodes2 };
};

//destructuring
let { dCodes: code1, dCodes2: code2 } = newCodes();

//now it can be accessed by code1 & code2
console.log(code1, code2);

Array Destructuring

In array destructuring, you can skip the values you don't need.

const newCodes = () => {  
    //...
    return [ dCodes, dCodes2, dCodes3 ];
};

let [ code1, code2 ] = newCodes(); //first two items
let [ code1, ,code3 ] = newCodes(); //skip middle item, get first & last
let [ ,, code3 ] = newCodes(); //skip first two items, get last
let [ code1, ...rest ] = newCodes(); //first item, and others as an array

It's worth noticing that ...rest should always be at the end as it doesn't make any sense to destruct anything after everything else is aggregated to rest.

I hope this will add some value to this question :)
