JavaScript Objects

In JavaScript, objects are king. If you understand objects, you understand JavaScript.

Creating an Object

You can create a JavaScript object using an object literal:

const person = {
  firstName: "John",
  lastName: "Doe",
  age: 50,
  eyeColor: "blue"
};

Accessing Object Properties

You can access object properties in two ways:

person.lastName;
// or
person["lastName"];
