Using fetch() in JavaScript


The fetch() function is the modern way to make API requests in JavaScript.

It allows your application to send requests to a server and receive data without reloading the page. This is how websites load user profiles, products, and live information.

Learning how to use fetch() is a must for every web developer working with APIs.

Why Use fetch()

  • It is built into modern browsers 
  • It works with promises
  • It supports all HTTP methods 
  • It handles JSON easily
  • It is widely used in real-world projects  

fetch() makes API communication simple and powerful.

This code sends a request to an API URL.

The response is converted into JSON format and then printed in the console.

Here, the code checks if the response is successful.

If something goes wrong, the error is caught and handled safely.

These examples show how fetch() is used to request data, handle responses, and manage errors.

By mastering fetch(), students gain the ability to connect their JavaScript applications to real servers and build professional, data-driven web applications.
