 Using these operators:
 
 - Promotes Immutability: Most array operators return new arrays, leaving the original array untouched. This functional approach helps prevent unintended side effects and makes your code more predictable.
-- Improves Readability: Chaining array operators often leads to more concise and expressive code than traditional for loops or imperative logic. The intent of the operation is clear at a glance.

 - Facilitates Functional Programming: These operators are cornerstones of functional programming, encouraging the creation of pure functions that take inputs and produce outputs without causing side effects. This paradigm is highly beneficial for writing robust and testable code that pairs well with React.
 
 By consistently applying these principles, we can maintain a codebase that is not only efficient and performant but also a joy to work with, both now and in the future.

 Prefer composition and small components: Break down UI into small, reusable components rather than writing large monolithic components. The code you generate should promote clarity and reusability by composing components together. Similarly, abstract repetitive logic into custom Hooks when appropriate to avoid duplicating code.
 
-Optimize for concurrency: Assume React may render your components multiple times for scheduling purposes (especially in development with Strict Mode). Write code that remains correct even if the component function runs more than once. For instance, avoid side effects in the component body and use functional state updates (e.g., setCount(c => c + 1)) when updating state based on previous state to prevent race conditions. Always include cleanup functions in effects that subscribe to external resources. Don't write useEffects for "do this when this changes" side-effects. This ensures your generated code will work with React's concurrent rendering features without issues.

 Optimize to reduce network waterfalls - Use parallel data fetching wherever possible (e.g., start multiple requests at once rather than one after another). Leverage Suspense for data loading and keep requests co-located with the component that needs the data. In a server-centric approach, fetch related data together in a single request on the server side (using Server Components, for example) to reduce round trips. Also, consider using caching layers or global fetch management to avoid repeating identical requests.
