PUT vs. PATCH

Comment

`PUT` and `PATCH` are both HTTP methods used for updating resources on the server, but they differ in their semantics and how they handle resource updates.

1. **PUT**:
   - `PUT` is used to update a resource or create it if it doesn't exist.
   - When you send a `PUT` request to a resource endpoint, you are replacing the entire resource with the new representation provided in the request payload.
   - If the resource doesn't exist at the specified URI, `PUT` will typically create a new resource with that URI.
   - `PUT` requests are idempotent, meaning that making the same request multiple times will have the same effect as making it once.
   - In other words, when you use `PUT`, you're essentially saying, "Here is the complete representation of the resource, update it or create it if it doesn't exist."

2. **PATCH**:
   - `PATCH` is used to apply partial modifications to a resource.
   - When you send a `PATCH` request to a resource endpoint, you are only providing the changes that need to be applied to the resource, rather than the entire representation.
   - `PATCH` requests are typically used when you want to update only certain fields of a resource without affecting the rest of its properties.
   - `PATCH` requests are also idempotent, meaning that applying the same patch multiple times will result in the same final state.
   - In summary, `PATCH` allows you to make partial updates to a resource, modifying only the specified fields.

In general, if you have all the data needed to update a resource, you can use `PUT` to send the entire new representation. If you only need to update specific fields of a resource, you can use `PATCH` to send a partial update.

PUT vs PATCH 
	PATCH is used to update an existing entity with new information. 
    You can’t patch an entity that doesn’t exist.
    
    PUT is used to set an entity’s information completely. PUTting is 
    similar to POSTing, except that it will overwrite the entity 
    if already exists or create it otherwise.

"put":
If I want to update my first name, then I send a put request:

{ "first": "Yus", "last": "Blah" } 
But here is a problem with using put request: When I want to send put request
I have to send all two parameters that is first and last (whereas I only need
to update first) so it is mandatory to send them all again with put request.

"patch":
patch request, on the other hand, says: only specify the data which you need 
to update and it won't be affecting or changing other data.
So no need to send all values again. Do I only need to change first name? 
Well, It only suffices to specify first in patch request.
