Understanding the core concepts of NgRx is crucial for leveraging its full potential in Angular applications. Let's break down the key components: Store:  The heart of NgRx, the Store is an immutable object holding your application's state. It can only be modified through dispatched actions, ensuring a controlled and predictable state management process. Actions: These are plain objects representing unique events or intents in your application. Actions are the messengers that trigger state changes, providing a clear trail of what's happening in your app. Reducers: Pure functions that take the current state and an action, then produce a new state. Reducers are the only place where state mutations occur in NgRx, maintaining predictability and traceability. Selectors: These pure functions select, derive, and compose pieces of state from the store. They provide a memoized way to access specific parts of the state, optimizing performance. Effects: Used for managing side e...

While the Virtual DOM is a powerful tool for improving React application performance, it's essential to understand optimization techniques to maximize its benefits. Understanding the Diffing Algorithm React's diffing algorithm is the heart of the Virtual DOM's efficiency. It compares the previous and new virtual DOM trees to determine minimal changes required for the real DOM. Key Optimization: React uses a heuristic approach to compare tree structures efficiently. It assumes that elements with different types have different children, and it only compares children for elements of the same type. Performance Optimization Techniques ShouldComponentUpdate: This lifecycle method allows you to control whether a component should re-render. By implementing custom logic, you can prevent unnecessary re-renders and improve performance. JavaScript shouldComponentUpdate ( nextProps, nextState ) { // Return true if component should update, false otherwise } PureComponent: This is ...
