How to solve the issue of lag when rendering a large amount of data in React?

When rendering a large amount of data in React, you may encounter lagging issues. Here are some suggestions to address the lagging problem:

1. Implement virtualization: By using virtualization libraries such as React Virtualized or React Window, only render the currently visible portion of data instead of all the data. This will reduce DOM operations and improve performance.
2. Paginate data: Divide data into multiple pages and render data using pagination loading. This can reduce the burden of rendering large amounts of data at once.
3. Utilize shouldComponentUpdate or React.memo in your components to prevent unnecessary re-rendering, so the component only re-renders when the data changes.
4. Utilize asynchronous rendering: dividing rendering tasks into smaller tasks and rendering data asynchronously can prevent lag caused by rendering a large amount of data at once.
5. Utilize Web Workers to offload data processing and rendering tasks from the main thread, thus avoiding blocking. By distributing rendering tasks across multiple threads, performance can be improved.
6. Optimize with PureComponent or React.memo: Use PureComponent or React.memo to optimize components and avoid unnecessary rendering.
7. Optimizing with keys: When rendering lists, make sure to provide a unique key value for each item in the list. This helps React identify which elements need to be updated, reducing unnecessary rendering.
8. Optimizing with window.requestAnimationFrame: Utilize requestAnimationFrame to delay rendering in order to prevent lag caused by rendering a large amount of data all at once.

Here are some common optimization techniques, choose the appropriate method based on the specific situation to resolve the issue of lagging caused by rendering a large amount of data.
