JS Practical Patterns

1. Using Factory functions to create object

function watchlistFactory(name){

 function createWatchlist(name){
  this.name = name;
  this.id = "wl_id_assoei02kdalik";
   return { name,id }
  }
  
  return createWatchlist(name);

}


let newWatchlist = new watchlistFactory("testWL2")
/*
{
  id: "wl_id_assoei02kdalik",
  name: "testWL2"
}
*/

2. Using setter and getters

const person = {
  firstName: "John",
  lastName: "Doe",
  language: "NO",
  set lang(value) {
    this.language = value;
  },
  set newProp(value) {
   this.newProperty = value
    }
};

person.lang = "english";
console.log(person.language)
person.newProp = "Property";
console.log(person.newProperty)

/*
"english"
"Property"
*/
