Can you explain how the HTTP protocol works from a Frontend developer's perspective?

From a Frontend developer's perspective, HTTP is a protocol for exchanging data between the client (browser) and the server.

When a user opens a web page, the browser sends an HTTP request (e.g., GET) to the server, indicating which resource it wants to retrieve. The server processes the request and returns an HTTP response with the required data (HTML, CSS, JS, images, etc.).

Main points:

• HTTP Methods: GET (retrieve data), POST (send data), PUT, DELETE, etc.
• Response Statuses: 200 (success), 404 (not found), 500 (server error), etc.
• Headers: contain meta-information, such as content type, cookies, authorization.

Frontend uses HTTP to load resources and interact with APIs, often through AJAX or fetch requests, to dynamically update the page without reloading.
