foo.js

module.exports = Foo;

//now i would like to have a constructor function for the foo "class" (i know in JS that does not exist)
//with normal js this would be

function Foo(arg1,arg2){
   this.something = arg1;
   this.somethingOther = arg2;
}

//but this would override exports, which defeats the purpose of putting this "class" in a different file

//would also like to do

Foo.prototype.fnc1 = function(args){
   //do stuff
}

//i learned that declaring "static" functions this way is a good practice in JS. Is that also possible with require?

require with prototyped objects

var Foo = require('./foo.js');

var foo1 = new Foo("x","y");
