What is an Object?

The object is a complex data type that allows you to represent real-world entities in a structured way. These entities can be people, things, concepts, or anything you can think of. Objects are sometimes called dictionaries because they consist of a collection of key-value pairs, where each key (also known as a property) has an associated value.

Let's take a closer look at this concept:

Anatomy of an Object

An object can be visualized as a container that holds data and behavior. It comprises key-value pairs, each key being a unique identifier, and the associated value can be of any data type, including other objects.

const person = {
  name: "Flora",
  age: 30,
  isStudent: false,
};

In this example, we have created an object person with three key-value pairs:

• The key name has the value "Flora";
• The key age has the value 30;
• The key isStudent has the value false.

Note

These key-value pairs describe the attributes of the person object. The keys are strings, and the values can be any valid JavaScript data type.

In the next chapter, we will focus on creating objects.
