The equivalent of method overloading in C# existing inTypeScript.

Behold:

function Speak(somethingToSay:string) {
   alert(somethingToSay);
}
function Speak(somethingToSay: string, isToSpeakLoudly: Boolean) {
   if (isToSpeakLoudly) {
      somethingToSay = somethingToSay.toUpperCase();
   }
   alert(somethingToSay);
}

 
 

Again, the one way which I have found that TypeScript is not to truly be a superset of JavaScript comes in an inability to call a function with fewer variables at the signature than are strictly specified without a compilation error. This is something that you may do in JavaScript and the missing variables towards the end just end up unset. What is above offers a way to compensate if you need this functionality.
