HTTP method PUT used to update an existing resource on the server or to create a new resource if it does not already exist. This method sends data to the server that replaces or updates the content of the specified resource according to the specified URL.
For example, if you have a web application to manage your task list and want to change the name of one of the tasks from "Clean at home" to "Clean in the room", you can use the PUT method. Your client code will send new data with an updated name to the server, and the server will replace the current information about this task with new data. If such a task does not exist, the server can create a new resource with the specified data. Thus, the PUT method allows the client to update or create resources on the server.
