Accessing Object Properties

There are two ways to access object properties:

objectName.propertyName

objectName[“propertyName”]

Example

person.lastName;

person[“lastName”];

JavaScript Object Methods

Methods are actions on objects, defined as functions stored in property values.

Property	Property Value
firstName	John
lastName	Doe
age	50
eyeColor	blue
fullName	function() {return this.firstName + ” ” + this.lastName;}

Example

const person = {
firstName: “John”,
lastName : “Doe”,
id       : 5566,
fullName : function() {
    return this.firstName + ” “ + this.lastName;
  }
};

In the example, this refers to the person object, with this.firstName and this.lastName accessing the person’s firstName and lastName properties.
