Dialogs, Popovers & the Top Layer Mess
- Dialogs (or modals) and popovers are essential UI components that interrupt the user's workflow to display critical information or offer interactive elements.
- The main challenge when using modals and popovers together is managing their stacking order.
- A proper solution would allow some popovers to remain exempt from the inert state and developers to manage the stacking order dynamically.
- Addressing stacking issues between dialogs and popovers can improve the web and create a more user-friendly experience.

Different ways of setting State in React
- useState hook in React is used to manage state in functional components.
- Setting Initial State: Initialize state by passing an initial value to useState.
- Updating State Based on Previous State: Use functional form of state setter to maintain up-to-date state.
- Updating Complex State: Use spread operator to update objects or arrays.
- Batching Multiple State Updates: React automatically batches updates for performance, but functional updates can be used for consistency.
- Lazy Initialization: Pass a function to useState for expensive initial state calculations.
- Resetting State: Store initial value in a variable to reset state.
- These methods provide flexibility in managing state in React applications.
