What is the difference?

Actually, what is the advantages of prototyping?

// this
const obj = {
  name : "Treehouse",
  is : "Learning site",
  work = function() {
    console.log("Teaching in better way");
  }
} 
// and this
const obj2 = {
  name : "Treehouse",
  is : "Learning site"
}
obj.prototype.work = function() {
  console.log("Teaching in better way");
}

One advantage is memory conservation. In the first case, every instance of the object will have it's own copy of the function. In the second, all instances will share the same function.

Also, with the prototype, you can redefine the function later and all instances will use the new one.
