Fetch is a web development tool used to retrieve data from the internet or send data to a server. It’s commonly used for tasks like getting information from an API or submitting data through a form.

How Does Fetch Work?

When you use the fetch() function, it sends a request to a specific server or API endpoint. Fetch works with promises, which let your code keep running while waiting for the server’s response. This makes it ideal for handling tasks without slowing down your application.

Fetch can handle various types of requests, such as:

• GET: Retrieve data from a server.
• POST: Send new data to a server.
• PUT: Update existing data.
• DELETE: Remove data from a server.

It also supports different data formats, including JSON, HTML, and plain text.

In simple terms, fetch makes it easier to communicate with servers, helping developers build dynamic and interactive applications.
