<ul data-eligibleForWebStory="true">When managing state in React, it's important to update it immutably to avoid bugs.Sharing state between components by lifting it to a common parent can help in keeping data in sync.It's advised to avoid managing the same data in multiple states and deriving values from props or existing state when possible.The Tic-Tac-Toe game discussed replays all turns to reconstruct the current state of the board.The game's logic is based on checking for winning combinations of 'X' or 'O' symbols in rows, columns, or diagonals.In React, JSX requires a single parent node per expression, leading to the need for careful structuring of components.Use of .map method in React for rendering elements can help create dynamic content.Avoid mutating the original state object directly in React to ensure proper re-rendering.React identifies changes by checking references, so updating state immutably is crucial for triggering re-renders.Working with React can be a challenging but rewarding experience, providing valuable insights into programming concepts and limitations.Despite the complexities, projects like building a Tic-Tac-Toe game in React serve as valuable learning experiences.
