Can you use any dummy API from the internet to fetch data for demonstration?

Yes, I can use a public dummy API to fetch data for a demo. Popular choices include JSONPlaceholder (https://jsonplaceholder.typicode.com/), which provides fake posts, comments, and users; ReqRes (https://reqres.in/), which offers endpoints for user authentication and pagination; and Mockaroo (https://mockaroo.com/), which lets me generate custom JSON schemas. I would typically use the Fetch API or a library like Axios in JavaScript to make GET requests. For example, to get a list of posts from JSONPlaceholder: fetch('https://jsonplaceholder.typicode.com/posts').then(res => res.json()).then(data => console.log(data));. I would handle loading states, errors, and parse the JSON response to populate UI components. Using these services eliminates the need for a backend during prototyping and allows me to focus on front‑end logic and data handling.
