How does React Reconciliation work?

Reconciliation is the process React uses to compare the old Virtual DOM with the new Virtual DOM.

Steps:

  1. Create new Virtual DOM
  2. Compare with previous Virtual DOM
  3. Identify changes
  4. Update only affected nodes in the real DOM

This process minimizes DOM operations and improves performance.
