Javascript adding setters in different scenarios

I am learning javascript(coming from php) and see there is multiple ways of class creation. Also learned about magic methods like get and set and i am wondering how they can be created in different scenarios (beside doing it when creating class with class keyword). Also i posted way of doing getter and setter in object literal and was wondering is there easier way. Here is code



//-------------------------------------------------------------------
//class
class create{
constructor(param1,param2){
this.name = param1;
this.name2 = param2;
}

fullname(){
console.log('...');
}

set name3(enteredValue){
this._name3 = enteredValue;
}
get name3(){
return this._name3;
}//This is how it is done in class
}
var obj2 = new create('test','test');

//-------------------------------------------------------------------
//object literal
var objLit = {
name: 'asas',
name2: 'assad'
}
Object.defineProperty(objLit, 'name3', {
get : function(){
return this._name3;
},
set : function(value){
this._name3 = value;
}
}); //This is how it is done in obj literal / Is there other way to do it in object?
//-------------------------------------------------------------------

//Factory Function
function createObj(param1, param2){
return{
name1: param1,
name2: param2,
fullName: function(){
console.log(this.name1+' '+this.name2);
}
}
}
var obj3 = createObj('Vukasin','Miljan');
//How to add setter in this scenario?


//-------------------------------------------------------------------

//Constructor function

function createObj2(param1,param2){
this.name1 = param1;
this.name2 = param2;
}
var obj4 = new createObj2('..','..');
//How to add setter in this scenario??

  • Your 2nd "object literal" code snippet already provides the solution for both your "Factory Function" and your "Constructor function" example. Make Object.defineProperty part of the factory and of the constructor. For the former you create objLit inside the factory, for the latter you are going to use the constructor's this context.

Adding getter/setter in the object:



let objLit = {
name: 'asas',
name2: 'assad',
get name3() {
return this._name3
},
set name3(value) {
this._name3 = value
}
}


In factory function:



function createObj(param1, param2) {
return {
set name1(value) {
param1 = value
},
set name2(value) {
param2 = value
},
get fullName() {
return `${param1} {param2}`
}
}
}
