responseIsSuccessStatusCode

The `responseIsSuccessStatusCode` function is a utility commonly found in web development libraries and frameworks. Its primary purpose is to determine whether an HTTP response received from a server indicates a successful operation.

HTTP status codes are three-digit numbers that communicate the outcome of a request. Codes in the 2xx range generally signify success. For example, a 200 OK status code means the request was successful, a 201 Created indicates a resource was successfully created, and a 204 No Content signifies that the request was successful but there is no content to send back.

The `responseIsSuccessStatusCode` function typically takes an HTTP status code as input and returns a boolean value. If the status code falls within the success range (e.g., 200-299), the function returns `true`. Otherwise, it returns `false`. This allows developers to easily check if an API call or web request yielded a positive result without having to manually check the status code against a range.

This function simplifies error handling and conditional logic. For instance, after making an API request, a developer can use `responseIsSuccessStatusCode` to decide whether to process the received data or display an error message to the user. This promotes cleaner and more readable code.
