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.
