React's useState vs useRef dilemma: because nothing tanks an investor demo like accidental re-renders or values ghosting the UI entirely

When working with React hooks, developers often face a dilemma in choosing between useState and useRef, two hooks that store values. The key difference lies in whether React should re-render when the value changes or not. useState is ideal for storing UI-related data, such as form values, counters, and toggles, as it triggers a re-render when updated. On the other hand, useRef is perfect for storing values without re-rendering the component, making it suitable for DOM access, like focusing on an HTML element. For instance, when the UI should react to a value change, useState is the better choice, whereas useRef is preferred when the UI does not need to update. This distinction is crucial in React development, as it directly impacts the performance and behavior of applications. By understanding the differences between useState and useRef, developers can create more efficient and effective React applications, enhancing the overall user experience.
