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         


        

Answer 1

In JS, we can easily return a tuple with an array or object, but do not forget! => JS is a callback oriented language, and there is a little secret here for "returning multiple values" that nobody has yet mentioned, try this:

var newCodes = function() {  
    var dCodes = fg.codecsCodes.rs;
    var dCodes2 = fg.codecsCodes2.rs;
    return dCodes, dCodes2;
};

becomes

var newCodes = function(fg, cb) {  
    var dCodes = fg.codecsCodes.rs;
    var dCodes2 = fg.codecsCodes2.rs;
    cb(null, dCodes, dCodes2);
};

:)

bam! This is simply another way of solving your problem.

Answer 2

A very common way to return multiple values in javascript is using an object literals, so something like:

const myFunction = () => {
  const firstName = "Alireza", 
        familyName = "Dezfoolian",
        age = 35;
  return { firstName, familyName, age};
}

and get the values like this:

myFunction().firstName; //Alireza
myFunction().familyName; //Dezfoolian
myFunction().age; //age

or even a shorter way:

const {firstName, familyName, age} = myFunction();

and get them individually like:

firstName; //Alireza
familyName; //Dezfoolian
age; //35
