jquery - Javascript Difference between normal function and function object -

In JavaScript, the way to create classes (or objects) is to use;

  function MyOn () {this.somevar = "xyz"; This is a common task ... how different is this function from a normal javascript function ... a function that adds 2 numbers?   
 
 
 The function is no different. For example, they have similar effects:  
  function myob () {this.somevar = "xyz"; This.someMethod = function () {console.log (this.someVar); }} Var obj = new MyObj (); Obj.someMethod ();   
 and  
  function someMethod () {console.log (this.someVar); } Function myob () {this.somevar = "xyz"; } Var obj = new MyObj (); SomeMethod.call (obj);   
 and  
  function someMethod () {console.log (this.someVar); } Function myob () {this.somevar = "xyz"; } Var obj = new MyObj (); Obj.f = someMethod; Obj.f ();   
 As you have tagged your question, I will finish by saying that the best way to make your function will be:  
  Function MyOne ( } {This.somevar = "xyz"; } MyObj.prototype.someMethod = function () {console.log (this.someVar); } Var obj = new MyObj (); Obj.someMethod ();   
 In this way, all the examples of  MyObj  do the same work and are lighter in this way.
