STOP using UseEffect for data fetching

UseEffect hook is a good choice for fetching data in small apps. However, for larger, more complex applications, it has several limitations.

• 𝗡𝗼 𝗰𝗮𝗰𝗵𝗶𝗻𝗴: Fetches data after every component mount.
• 𝗟𝗼𝗮𝗱𝗶𝗻𝗴 𝘀𝘁𝗮𝘁𝗲 needs to be tracked manually.
• No built-in error handling.

As a result of the above limitations, you often write a lot of repetitive code to handle loading states, errors, and data management.
