Creating Objects in JavaScript

js

There are 2 ways to create objects in Javascript: literal notation and constructor notation.

I’ll demonstrate below how to create the same object using each method.

Literal Notation

var pig = {
  name: "Porkster",
  age: 5,
  size: "Large",
  favoriteFood: "Slop"
};

Constructor Notation

var pig = new Object();
pig.name = "Porkster";
pig.age = 5;
pig.size = "Large";
pig.favoriteFood = "Slop";

It actually depends on you which one you use. Obviously constructor notation requires more characters to type but remember that you can combine the two. You can start by using literal notation and just add properties later using dots:

var cow = {
  name: "Holy",
  age: 2
}
cow.color = "Black and White";
cow.gender = "Female";

So it’s up to you. πŸ™‚
