Keys in List (in Hindi) - opendevs

React.js Course 2023 - React js tutorial

https://opendevs.in Discord: https://discord.gg/bJC3hYwNHj This video show you how to use keys in list and why are they required to render lists in react. A “key” is a special string attribute you need to include when creating lists of elements. Keys help React identify which items have changed, are added, or are removed. Keys should be given to the elements inside the array to give the elements a stable identity. The best way to pick a key is to use a string that uniquely identifies a list item among its siblings. Most often you would use IDs from your data as keys. When you don’t have stable IDs for rendered items, you may use the item index as a key as a last resort. ====== Development guides ====== React Docs: https://reactjs.org/docs/getting-started.html VS Code setup: https://code.visualstudio.com/learn/get-started/basics Node.js setup: https://nodejs.org/en/download/ ====== opendevs Links ====== Website: https://opendevs.in Contact us: https://opendevs.in/contact Our website offers React course with practice problems & code submissions.
