Multiple return in one function (javascript) [duplicate]

Question

function myFunction() {
    if (condition)
        return a;
    return b;
}

In this case if the condition is true, both a and b will be returned or only a is returned.

only a will be returned as The return statement stops the execution of a function — Kevin Kloet

do somthing like that return [a, b]; or like that return { a: a, b: b }; — MMK

For such a trivial question, it was way faster to build a simple test case than asking for an answer here… — Sxilderik

If the condition is true, only a is returned.

No curly brace means only the next statement is exectuted after the if.

Only the first return is executed, then the flow is returned in the case the if condition is met..

Try it yourself like below in browser console.

(function()
{
var f1= function(condition){
  if(condition>1)
     return "a"
     return "b"
    };  

var result=  f1(3)
console.log(result)

}());

you can return result as array or object
example:

function myFunction()
{
    if (condition){ 
        return [a,b]; 
    }else{ 
        return [b]; 
    } 
 }
