This document outlines the approaches and considerations for integrating RFC 9457 (error response handling) into our application. The aim is to handle network error responses appropriately while enhancing user experience. Specifically, this design covers the handling of Retry-After headers for specific status codes (429 and 503) and 301 redirect responses with URLs.

Additionally, RFC 9457 also aims to convey more descriptive error messages to both users and developers, ensuring clarity and improved troubleshooting capabilities.

becuase in order for react to work properly, on each render, each hook should be called with the same order that it was called before.That’s what allows React to correctly preserve the state of Hooks between multiple calls.
for each hook in a react component there is an Object called "memory cell". When we call a Hook like useState(), it reads the current cell (or initializes it during the first render), and then moves the pointer to the next one. This is how multiple useState() calls each get independent local state.
under the hood hooks are implemented like a LinkedList where each one represents a node having reference to the next one.

Koa middleware cascade in a more traditional way as you may be used to with similar tools - this was previously difficult to make user friendly with node's use of callbacks. However with async functions we can achieve "true" middleware. Contrasting Connect's implementation which simply passes control through series of functions until one returns, Koa invoke "downstream", then control flows back "upstream".

The following example responds with "Hello World", however first the request flows through the x-response-time and logging middleware to mark when the request started, then continue to yield control through the response middleware. When a middleware invokes next() the function suspends and passes control to the next middleware defined. After there are no more middleware to execute downstream, the stack will unwind and each middleware is resumed to perform its upstream behaviour.
