Component Lifecycle: Updating

The component still re-renders but skips componentDidUpdate
The component update process is completely skipped
If shouldComponentUpdate() returns false, the component update process is completely skipped. This means render(), getSnapshotBeforeUpdate(), and componentDidUpdate() will not be invoked, and neither the component nor any of its children will re-render. This is useful for performance optimization when you know a render is unnecessary.
The component will throw an error
The component will still update its DOM representation
