Use Maps More and Objects Less
Objects in JavaScript can be replaced with maps for better performance, easier iteration, and key-value manipulation. Maps are optimized for frequently adding and removing keys, unlike objects. They also solve issues of objects being polluted with built-in keys and provide better iteration methods. Maps can be easily copied, converted to objects, and vice versa. They can also be used for associating metadata with objects. Sets, another similar data structure, provide a better-performing way to create unique lists of elements.

useSignal() is the Future of Web Frameworks
Signals are a reactive way to store and track state in an application. They return a getter and a setter, unlike non-reactive systems which only return a value and a setter. This allows for more efficient updates and prevents unnecessary re-renders in the UI. In contrast, React's useState() returns only the state value and lacks the subscription tracking and notification features of Signals. Overall, Signals provide a more efficient and reactive approach to state management in web frameworks.
