Fetch

Fetch is a tool used in web development. It helps to retrieve data from the internet or send data to a server. Imagine you want to get data from an API or submit a form to a server – fetch is what you’d use to handle these tasks.

How Does Fetch Work?

When you use fetch(), you send a request, often in the form of HTTP call, to the API endpoint. Fetch works with something called promises – it’s a way to handle what happens after you make the request. This means you can continue working on other parts of your code while waiting for the response from the server.

Fetch can handle different types of requests like asking for data (GET), sending new (POST), updating existing (PUT), or deleting (DELETE) data. It’s flexible and can work with various data formats, such as JSON or HTML.

In short, fetch() method simplifies the process of communicating with servers and handling data, letting you build more dynamic and interactive web applications.
