Fetch API in JavaScript


  The Fetch API in JavaScript allows you to makeHTTP requests (like `GET`, `POST`, among others) to interact with servers and retrieve or send data.


Syntax:


  The basic syntax of the Fetch API is as follows:

  • fetch(url): Used to make a `GET` request by default.

  • fetch(url, options): Can be used to customize the request, such as using the `POST` method or sending data.

  Example of a `GET` request:

fetch('https://api.example.com/data')


  Example of a `POST` request:

`

fetch('https://api.example.com/data', { method: 'POST', body: JSON.stringify({ key: 'value' }) })

`

Purpose:

  • Retrieve data from servers using HTTP requests.
  • Send data to a server using the `POST` method.
  • Interact with external APIs to retrieve information.
