Working with REST APIs in JavaScript

Fetching data from external APIs is a common task in web development. JavaScript’s built-in fetch API makes this simple and promise-based.

Why use fetch?

• Modern & Native: No need for external libraries.
• Promise-based: Cleaner syntax using async/await.
• Flexible: Supports GET, POST, PUT, DELETE, and more.

Example

Here's how to fetch data from an API:

async function getPosts() {
  const response = await fetch('https://jsonplaceholder.typicode.com/posts');
  const data = await response.json();
  console.log(data);
}
getPosts();
