JSON stands for JavaScript Object Notation.
It is a text-based, open standard data format used for storing and transmitting data.
We can also describe it as a human-readable text format that uses JavaScript object notation.

Below you can see a sample JSON object.
It's an object with property value pairs.
As you can see, the JSON is similar to classic Javascript objects, which makes it easy to manipulate in Javascript code.

Sometimes you may find it useful to use the prettified output (e.g. output to console).
For this stringify uses the third parameter that specifies the spacing level.

APIs widely use JSON to send a payload to a server and receive the resource data.
If we compare it with XML it's much easier to read and it uses less bandwidth.
Below you can see a sample fetch request for posting JSON data to the API.
