HTTP Methods Overview
Definition
Standardized 'verbs' used in HTTP requests to indicate the desired action to be performed on a specific resource.
Explain Like I'm New
If you send a request to `/api/users`, the server needs to know what you want to do. GET = Read users. POST = Create a new user. DELETE = Destroy a user. PUT = Replace a user.
Real World Example
Building a CRUD (Create, Read, Update, Delete) application. Each letter perfectly maps to an HTTP Method: Create (POST), Read (GET), Update (PUT/PATCH), Delete (DELETE).
