You can't do that.

But, you can return an array or an object which contains your values.

function doSomething(a,b){
    return [a,b];
  //return {a,b};
}
console.log(doSomething(1,2));

If you want to return many values you can use destructing operator in order to find out all the values.

function doSomething(a,b,c,d,e,f){
      return {a,b,c,d,e,f};
}
let {a,b,c,d,e,f}=doSomething(1,2,3,4,5,6);
console.log(a,b,c,d,e,f);

What the method return type would be if we wanted to see it in the signature ?

Functions by definition can only return one value. However, you can pack your values in an array or an object:

function greeting(){
    return {
        name: "Andy",
        message: "Hello world"
    };
}
