Overview of all HTTP methods including GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS, and CONNECT. Each method is represented with its purpose — for example, GET for retrieving data, POST for creating resources, PUT for replacing data, PATCH for partial updates, DELETE for removing resources, HEAD for metadata, OPTIONS for supported operations, and CONNECT for tunneling. Useful for understanding RESTful API operations.

All HTTP Request Methods

HTTP requests are how your app talks to a server to send or get data. For example, when a user logs in or loads a list of posts, the app makes an HTTP request to the server. There are different types of requests: GET to fetch data, POST to send new data, PUT/PATCH to update, and DELETE to remove. These requests are sent over the internet using the HTTP protocol. In JavaScript, you can make these requests using tools like fetch or libraries like Axios. It's a key part of building apps that work with APIs or backends.

HTTP requests

The difference between using HTTP and HTTPS for website security, particularly when transmitting sensitive data like passwords.

HTTP vs HTTPS

In React, you can share data between components using props or the Context API. Props are used to pass data from one component to another, like from parent to child. This works well when only a few components need the data. But if many components need the same data, and they are deep in the tree, passing props through every level becomes messy—this is called prop drilling. The Context API helps with this by letting you share data across your app without passing it through every level. Use props for simple, direct sharing, and Context when many parts of your app need the same data.
