How to “properly” create a custom object in JavaScript?

Question

I wonder about what the best way is to create an JavaScript object that has properties and methods.

I have seen examples where the person used var self = this<

Answer 1

Bascially there is no concept of class in JS so we use function as a class constructor which is relevant with the existing design patterns.

//Constructor Pattern
function Person(name, age, job){
 this.name = name;
 this.age = age;
 this.job = job;
 this.doSomething = function(){
    alert('I am Happy');
}
}

Till now JS has no clue that you want to create an object so here comes the new keyword.

var person1 = new Person('Arv', 30, 'Software');
person1.name //Arv
