You notice that a component wrapped with a Context.Consumer is re-rendering excessively, even when the context values it consumes have not changed. What strategy can you employ to optimize the component's performance?

  • Increase the context provider's update interval to reduce the frequency of context updates.
  • Split the component into smaller sub-components, each with its own Context.Consumer, to isolate updates.
  • Use React.memo to wrap the component and prevent unnecessary re-renders.
  • Use shouldComponentUpdate lifecycle method to manually control re-renders based on context changes.
To optimize the performance of a component that re-renders excessively when using Context.Consumer, you can use React.memo. React.memo will prevent unnecessary re-renders by memoizing the component. Splitting the component into smaller sub-components or using shouldComponentUpdate manually can be complex and error-prone. Increasing the context provider's update interval is not a standard practice and may have unintended consequences.
