JSON Object -

The JSON object is written inside curly braces `{ }`. JSON objects can contain multiple "key/value" pairs.

Accessing JSON Data -

You can access JSON data using the dot notation.

Converting JavaScript Object to JSON -

JSON is the most commonly used format for transmitting data (data interchange) from a server to a client and vice-versa.

JSON data are very easy to parse and use. It is fast to access and manipulate JSON data as they only contain text.
