🚀 React Most Asked Interview Question: How do you pass data from a Child Component back to a Parent Component? This is one of the most common concepts every React developer must know — and interviewers love to ask it! In this video, I explained this concept in the simplest way: 🔹 Parent creates a function 🔹 Function is passed to the child as a prop 🔹 Child calls the function and sends the data back 🔹 Parent receives that data and updates its state This technique is called “Lifting State Up” — and it helps keep your components clean, manageable, and predictable. Hope this video helps beginners and job-seekers understand this important React concept more clearly! 💡 #reactjs #reactdeveloper #frontenddevelopment #javascript #webdevelopment #interviewpreparation #reactinterview #codingtips
