In terms of performance optimization, how does Redux's connect method help in preventing unnecessary re-renders?

  • It uses a shallow equality check to compare previous and current state.
  • It automatically memoizes the component's render function.
  • It prevents the component from re-rendering entirely.
  • It relies on PureComponent for optimization.
Redux's connect method helps prevent unnecessary re-renders by automatically memoizing the component's render function. This memoization optimizes rendering performance by preventing re-renders when the component's props or state haven't changed. The other options do not accurately describe how Redux's connect method achieves this optimization.
