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.

𝗟𝗶𝗺𝗶𝘁𝗮𝘁𝗶𝗼𝗻𝘀 𝗼𝗳 𝘂𝘀𝗲𝗘𝗳𝗳𝗲𝗰𝘁 𝗳𝗼𝗿 𝗱𝗮𝘁𝗮 𝗳𝗲𝘁𝗰𝗵𝗶𝗻𝗴:

• 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.
