In Js, the event loop is a key feature that handles asynchronous code execution. Call stack handles synchronous code.
Asynchronous code (promise,setTimeo) is sent to Web APIs.
Once complete, they move to the task queue and wait to be pushed back to the call stack when it's empty.
React's Virtual DOM is a game-changer for efficient rendering! ⚡ It acts as a lightweight copy of the real DOM, allowing React to compare changes (using the diffing algorithm) and update only the necessary parts of the actual DOM.
How do you optimize React apps?👇
JavaScript’s Event Loop handles asynchronous tasks like a pro! 🌀 It manages tasks between the Call Stack, Message Queue, and Microtask Queue. Tasks like setTimeout go into the Message Queue, while promises and other microtasks are prioritized in the Microtask Queue. 🔄
React’s reconciliation algorithm efficiently updates the UI by using a Virtual DOM. Instead of updating the real DOM every time, React compares the current and previous Virtual DOM trees using a process called diffing and applies only the necessary changes! 🌳⚡
Redux centralizes state management in React applications, making your app’s state predictable & maintainable!🔄
📊 Actions trigger changes, reducers update the state, and the store keeps everything in sync! Say goodbye to prop drilling with Redux's clean & scalable architecture🛠️
React’s Virtual DOM is a performance booster, making UI updates lightning fast ⚡ by only changing the parts of the DOM that need updates! 🚀
This is what makes React apps so efficient. Have you optimized your UI lately? Let’s talk performance! 👇
