List And Keys in React JS - Rendering Loop in React Hindi / Urdu Tutorial
In this React JS tutorial in Hindi/Urdu, you will learn about "List and Keys" in React. List and Keys are two important concepts in React that help in rendering loops in a more efficient way. This video will cover the basics of List and Keys and how they work together to make React more powerful.
A “key” is a special string attribute you need to include when creating lists of elements.
Keys give the elements a stable identity.
Keys help React identify which items have changed, are added, or are removed.
This results in a much more efficient update of the user interface.
