How in javascript to implement a function that is called as a string?

Question

I need to implement a function that is called as a string, how to do this better? An example of a call might look like this:

var a = ‘Hi’.myFunc();
console.log(a); // Hi

You want to add a method to `String.prototype`…? But then again, you don't need that if you just want `a` to be `'Hi'`… — deceze, Aug 22 '17 at 09:54
You need to add a function to String.prototype. [Look it](https://stackoverflow.com/questions/8392035/javascript-add-method-to-string-class), it should help — Rafał Gołubowicz, Aug 22 '17 at 09:55
If you want to manipulate the string you can do something like this: http://jsbin.com/xacoyut/edit?js,console — Mosh Feu, Aug 22 '17 at 10:02

String.prototype.myFunc= function(){
   return this.toString()
}

var a = 'Hi'.myFunc();
console.log(a); // Hi

Here is your solution to attach a function to any String

String.prototype.coucou = function(){
 console.log("coucou")   
}

"a".coucou()  //print "coucou" in console
