Classical (non-js) approach to overloading:

function myFunc(){
 //code
}

function myFunc(overloaded){
 //other code
}

Javascript wont let more than one function be defined with the same name. As such, things like this show up:

function myFunc(options){
 if(options["overloaded"]){
  //code
 }
}

Is there a better workaround for function overloading in javascript other than passing an object with the overloads in it?

Passing in overloads can quickly cause a function to become too verbose because each possible overload would then need a conditional statement. Using functions to accomplish the //code inside of those conditional statements can cause tricky situations with scopes.
