How is the easiest way to check if the response to the request is succesful or not?

Question

I need a simple synchronous function that checks if the response to a specific url is successful or returns an error, for example 404.

For example:

https://api.com/articles/1 -> response returns sth with code 200

https://api.com/articles/1 -> response returns error 404

As it was already mentioned in the question, you can check the response status.

• 2xx statuses considered as successful,
• 3xx can be also turn out as successful, you should use followRedirect.

Depends on the API, it can return with success status, while the response body has content which could still mean an error.
